I recognized the feeling/fear of going insane. One of my mushroom trips I had the same thing - not exactly fun. I'm not really interested in trying LSD due to the trip lasting longer - 4 hours (mushrooms) of pure fear is enough. Yes, I've had good trips too, but about half of them went bad at some point and that ain't fun.

In general, only take hallucinogenics if you're in a good, stable place... Not when you're worried or afraid of something.
