What are shrooms and mescaline like?

I've tripped on different sh*t like acid, nitrous, dxm. i honestly think the dxm (which was from coriciden) was the most intense. nitrous is just a really f*cked up, funny a**, geeked out 30 second trip. acid is just a chill vision f*ck. goes real good with lots of pot. im not condoning to drug use or anything. i just wanna learn more about shrooms and mescaline. plus whats the difference with psylocibin and amanitas shrooms? nobody really gives a real good discription of what its like. i get the "i can't describe it" thing, but i would think you could describe the physical feelings and what the experience was like in some way. so any description or shared experience would be helpful cause
