Is it possible to have ego-death in combination with a bad trip?
More than 20 years ago, a group of friends and I each consumed 30 fresh p. subs. That was easily the wildest ride of my psychedelic career. The peak for me was a bad trip. With my eyes open, I couldn't see anything that resembled reality. Worse, the stereo was a busted record player that kept playing the first side of Pink Floyd's "Animals" (i.e. the track "Dogs") over and over, probably the worst tripping music you could imagine.
The effect on me was shattering. I stood outside myself, and I didn't like what I saw. Up until that day, I had a lot of self-confidence, but the mushrooms blew it all away. At the time, when I had come down, I thought "well, I'll never have 30 mushrooms again". But in retrospect, I think that experience altered my whole life, and not in a positive way.
I enjoy reading the reports of the psychonauts on this forum, and goodwill to all of them, but be aware that ther is potentially a dark side.
My last trip (san pedro) was about five years ago. I encountered an entity that basically told me to "fuck off". I've accepted his advice.
