Not so long ago I smoked way too much and ended up tripping out. A couple days after my trip I had a hard time believing that I was actually alive I thought I was dead but I realized no one had ever died from weed so it was just in my head. Ever since then my dreams a much more vivid I get in my head A LOT. Thinking about the worlds existence and life after death. It's just scaring me now I do think the bad trip caused me to get anxiety so now I'm just a ball of worry. What should I do to stop this ?
Quit being a worry wart. Just suck it up, you can't do anything except accept your situation. You can accept it or whine about it, your choice.
Life is a process of confronting your existential fears and thinking your way through them. Sometimes Mother Nature will splash water in your sleeping face. Just trust the process, and unless you're having a full out panic attack (which can happen to some) feel free to keep smoking.
