I've heard plenty of people thinking they've gone to another universe, reality, dimension, spirit world etc. just remember, there's no limit to what the mind can believe or experience, and there's no limit to how real and sure it can seem. but in the end, it's all just chemicals fucking with your brain. CHEMICALS, little bits of molecules that send incorrect information to your neurons to no limit. don't ever fall for that crap that you're being given powers or super mental abilities or any of that stuff, as so many do.
