I've took shrooms last week-end that was my second time, and it was amazing. 

You can can really tell if you pay enough attention, that is some sort of presence out there, watching you during your trip! 

I remember that I asked to this entity to show me what it can do, and it replied to me with visuals when my eyes were closed. The visuals were changing when IT showed me different aspects of the trip. Geometrical forms, lot of bright colors, worm sensations in my whole body when my mind drifted to pleasent thoughts, and when my mind had dark thoughts, one big red octopus trying to surround me with its tentacles, and total darkness. It was like a warning, like if the mushroom was telling me that tripping could enlight me but if I wasn't respectful enough it could destroy me. 

Shrooms is an amazing experience truly, one of the best things I've ever experienced in my life!
