Your description of what LSD feels like tracks well with what I experienced on very low doses, but taking high doses entails much more than what you described.

I've had to babysit friends that completely lost touch with reality, deal with someone going into a seizure while peaking, and try my best to keep it together while dealing with uncomfortable hallucinations like seeing eyes EVERYWHERE or having the road crumple in on itself.

Not to mention my brain felt like complete mush on high doses of LSD. Sure, I had some profound spiritual thoughts, but it also made me feel stupid because I couldn't communicate what I was thinking and even doing simple things like trying to turn off music on my laptop became monumental tasks.
