First Changa Experience

So I had my first experience with Changa a few days ago and its incredible to say the least. My brother packed up a bowl of some very potent Changa and I just sat on the bed and took the first hit and within 2 seconds there was a tingling/numbing sensation throughout my whole body. All of the things on the walls were very 3D and geometric. About 10 seconds after I took the first hit, I took a big one and that's when I blasted off. I laid back on the bed and closed my eyes and I was immediately greeted by 2 or 3 beings or entities. they were greenish/blue in color, and they almost looked like a pharaohs head. I don't remember much of the trip but from what I do remember, I was just following them on a journey through space and time. I was at a Stonehenge like place at one point, and I saw what looked like an Easter island head. There was a tremendous amount of colors, it was breathtaking. The most profound part of my experience that is imprinted in my mind was as I was coming out of the trip, right before I opened my eyes, one of the entities got up close to my face, and put their pointer finger over their mouth as if they were saying "Shhh" like they had told me the secrets to the universe and then wiped my mind clean. I then opened my eyes and was confused as to where I was. My brother and his girlfriend were sitting near by and I asked them how long I was gone and they said only 10 minutes. After that, everything was very wavy and spacey for the next 20 minutes or so. Definitely the best experience of my life. I wish I could remember more of the trip.
