A favorite thing to do was stare at trees while tripping. They are an excellent visual study of a way natural objects arrange themselves fractally, some neat mathematics behind their geometry. One of my most profound experiences involved a telepathic communications between myself and a divine consciousness connected through my favorite tree in the backyard.

You take a picture of the tree to remember later....and it was just an ordinary bush.

Honestly this pic kinda reminds me of acid visuals already lol.

I once saw this when stoned except that it was tree fractals

Maybe it would cancel out and be the only normal looking tree you see 😂
