The most common and clearest content of the flashbacks seems to involve the visual sensory system, but flashbacks have been reported in any sensory modality: taste, smell, touch, kinesthetics, vestibular changes, and auditory images. In addition, distortions of time sense, self-image, or reality sense may occur. This paper describes the visual forms of this symptom and compares it with known symptoms such as obsessive rumination, peremptory ideation, and recurrent pseudo-hallucinations.
Description of Flashbacks Flashbacks (flashes, flashing) may persist for weeks or months after the last drug experience. The most important variety is repeated intrusions of frightening images in spite of volitional efforts to avoid them. However, two lesser variants can be described briefly.
Spontaneous Return of Perceptual Distortions Distortions of perception experienced during the drug experience may recur long afterward, as previously reported(2). Subjective experiences include halo effects, blurred vision, shimmering, or reduplications of percepts, distortion of spatial planes, and changes in normal coloration. Micropsia, macropsia, and tunnel vision may also appear during the period "off" drugs. Examples of such perceptual distortions and elementary sensations are:
Patient A: Now I often see a bright shiny halo around people, especially at the dark edges-sometimes it's rainbow colors-like during the trip.
Patient B: Sometimes the sidewalk seems to bend as if it's going downwards--even when I'm not on anything-or it just kinda vibrates back and forth.
Increased Susceptibility to Spontaneous Imagery Some persons report that after repeated use of hallucinogens they find visual imagery occupies a greater proportion of their thinking than formerly. They also state that their imagery now has a different quality-it is more vivid, seems to spring from some nonvolitional source, and is less readily suppressed than formerly. The incidence of this type of flashback appears related to total dose over time.
Patient C: I see this giant iguana, all the time, man. Green. In corners. Like under your chair.
Doctor: Are you putting me on about that?
Patient C: No---you mean about under your chair like? No. I see it all right-sometimes even when I want to. It used to be fierce; now it's friendly.
Doctor: Used to be fierce?
Patient C: Well, like when I first had it-it was a monster from the dark lagoon and then it came at me sometimes. But now it's okay.
Doctor. Well, didn't you see stuff like that in your mind's eye all the time before any trips?
Patient C: Not like this, man. Not like this-it's real green.
Doctor: You mean, it's different?
Patient C: Oh, I see other things-this one's different-more so, I guess, more often, and clearer.
Patient D: Now I see things-walls, and faces, and caves-probably imprinted on my thalamus from the prehistoric past. Sometimes as clear as on a trip, but mostly not. My dreams sometimes are really spectacular now.
Recurrent Unbidden Images Unbidden images are those that repeatedly coerce their way into awareness, demanding attention and resisting efforts to dispel them. They have been described by those who experience them as having "a will of their own." Some persons are frightened by their incapacity to dispel the images. Anxiety reactions, even psychotic reactions, may result.
Case Reports The following three case reports the recurrent and unbidden imagery flashbacks.
Case 1. This 17-year-old boy had taken marihuana, dimethyltriptamine (DMT), methedrine, LSD, and LSD with arsenic ("for that special kick"). Although his behavior was noted by his friends to be "freaky when he was flashing," he was able to deliver his thoughts in a rational manner. He described his therme song as "LSD and Speed Are All That There Is for Me" and spent most of his time drawing morbid and bizarre references to death. His costume was black with steel link chains. During a recent "trip" he hallucinated a dark scorpion on the back of his hand and experienced terror: "It had many legs, and I was worried it might sting me." In the past five weeks - since the "trip" he claims to have ingested no drugs, but the scorpion continues as "flashings," sometimes in a changed position, but always brown or black in color.
Case 2. This 21 -year-old man had numerously trips on LSD and marihuana. He described himself as preoccupied with life and death. After taking 2.5-dimethoxy-4-methyl amphetamine (STP) for the first time, he had repeated visual and kinesthetic images of himself crashing through the window of his car. He had never had such an accident in reality, yet during the flashbacks he felt fear at vividness of the experience. He was sensitive about his flashback and said it was not a symptom but a "release of the within" from the drug. The image appeared symbolic of repressed fears of losing control and of destructiveness.
Case 3. A 16-year-old male high school dropout living in the Haight-Ashbury community reported an estimated ten LSD trips and 100 marihuana smokings. He denied use of other drugs. Generally, during LSD trips he experienced interesting, wild, intense, and usually pleasant visual imagery. Recently, however, he had a "bad trip" with images of a human figure being sucked into the vortex of a whirlpool. This image began returning three weeks after the LSD trip and persisted for about three additional weeks. Five to ten times a day the vivid black and white images interrupted whatever he was thinking. These images were more pressing when he was "high" on marihuana. Whenever he had the flashback, he felt frightened and unsuccessfully tried to get rid of it. Although the time seemed very long, he knew that after approximately 15 to 20 seconds the image would leave of its own accord.

at work we have this white opaque underlit bar, at times depending on whats running the electrical flow will flicker. that shit strains the hell out of my eyes and reminds me of the vivid flashing you get at times from LSD.
nothing i have dealt with would be considered a flashback though.

Most of that description is HPPD, or something too mild to even separate from placebo / misc brain farts.
The people being interviewed sound very far from credible, I'll take the extensive experience of a dozen shroomerites and a hundred psychonauts I've met over those random shortbussers.

Back when i was taking quite a few different RC tryptamines/phenethylamines like once a week, i was dead sober in a doctors office and all of a sudden the floor just turned into water for like 30 seconds. That was about as crazy as it ever got. Would also be sober and be reading something and get the classic breathing/floating of letters on the background.
It was always visual too and not mental at all.

Some of what's been described are things i've personally experienced. As for the DSM, flashbacks are listed along side HPPD and may be two names for the same symptomatic phenomenon, and is experientially subjective

Never had a "true hallucinogenic flashback" but Ive had times where things would remind me and take me back to a certain time i tripped. For example when I eat watermelon it brings me back to one time I tripped stupid hard and ate some watermelon that I thought was some type of raw animal meat from looking into the fleshy watermelon so much. Even if I were to stare at some watermelon to this day I could probably get the feelings I once had on that acid trip lol
