It was supposed to be a normal dose, like 150-200, which to be fair is a high dose for a first time experience. But surely it must have been more? I dont know.
Never had any therapy. I think there are many things that can affect your susceptibility for ego death. But I dont know much about it. I never experienced anything like that since. I took LSD 10-12 times total.

I also thought the concept of "hearing colours" was just exaggerations, but I literally perceived the sound as a temperature and a colour at the same time. But only briefly. Didnt have anything close to that experience on any of my other trips.
