You don't usually see/think that shit until you get around a quarter. The shit you see before getting to "extreme" doses is more of flowing and movement rather than replacements of objects with other objects. Actually, I believe it's pretty rare to see replacements of etc. etc. except on drugs like Datura and PCP?
I always thought that was more of an acid thing. I just float around on high doses of acid (float through the universe) and on shrooms I walk in this bubble - kind of like watching TV. As much as you do care, you just don't..
It seems to me psychedelics only become dangerous when you believe the shit the government puts out about them.I remember way back when I had my first psychedelic experience I didn't know much about them and I wasn't sure what to expect since I always heard stories from the damn governmant about people jumping out windows and cutting themselves up.Turns out since I had this shit stuck in the back of my mind I ended up having a bad trip which was focused on really weird and freaky stuff because I still had that propaganda stuck in my train of thought. My point is the it's the government themselves who contribute to people having dangerous trips by freaking people out with their bullshit stories.So just don't listen to the propaganda and you'll be fine.
