I did have a reasonably strong experience with morning glory seeds. It was the first attempt at a psychedelic, and since then I've become more interested in them because the effects were distinctly different from anything else I've tried. I did the basic naptha and everclear extraction.
The first thing I noticed on the come up was that I felt energized and talkative. Everything seemed ridiculous and hilarious. The visuals began with purple and green colors spreading away from bright lights. Next my entire vision started to flicker green and purple, and I was seeing faint patterns. After a long slow ramp up, the visuals turned into a 2d grid of triangle superimposed over my vision. The patterns stayed in the same place no matter where I looked, and colors radiated out of the triangles.
I hit the peak somewhere around 6 hours in. At a certain point, if looked at something long enough my entire vision would pixelate into large single color triangles. From this point on I could tell things were about to get more serious. I started to get this powerful sensation that all of my thoughts and senses were getting oscillated. I spent almost all of this time with my eyes closed. At first I had a bit anxiety about the fact that I didn't feel like I needed breath. Soon I went into ego death and I was leaving my body and traveling through a universe of 3d rotating triangles. I'm not really sure how long this lasted, but it wasn't that difficult to handle.
