I didn't see entities, but I experienced a kundalini awakening, ie energy rising up spine and exploding into light from my third eye, everything was energy, resonating with a single syllable which was repeating itself endlessly without ever starting or stopping, there was light streaming from my hands and eyes and absolutely no differentiation between myself as a 'person' and the external world. At the peak the only way I can describe it is that my perception of the world and senses became that of a snake. It took over 6 months to 'come down' from that and the only reason I didn't get institutionalised is because I had shit friends and none of them reported their concern, they just laughed at me. I was 100% certifiably psychotic the entire time following it. Please reconsider taking heaps of acid and gunning for a third eye awakening, if that's what you're doing. That's what Tool were talking about in that song yeah, prying open the third eye rather than letting it open. There are consequences. I can't in good faith recommend you did what I have, as annoying as that is. Take acid by all means, it'll show you 'a way' but it is not THE way. It's a great way to lose your mind and become incredibly conceited. I was convinced that I had reached some form of enlightenment but in reality I was drinking to blackout every day, taking pills and smoking meth, unemployed and not showering for up to and over a week at a time. I've seen a lot of that at festivals tbh, I used to participate in the psytrance scene but I seriously can't go to doofs anymore because I see a lot of people who think k-holing every weekend is showing them something about 'the universe.' Correct method of third eye awakening is meditation and nofap (called brahmacharya in Hindu terminology,) friend it's a lot slower but the results are the same, sustainable and once it happens it's there for good. With all that said, fuck yeah try it IF YOU DO NOT HAVE A HISTORY OF SCHIZOPHRENIA IN YOUR FAMILY DO NOT TAKE THE ACID IF YOU HAVE THE SCHIZOPHRENIA IN YOUR FAMILY But please be careful. I really don't want to condone drug use because it can be a really deep and shit hole to dig yourself out of. But there are some benefits if you do as Alan Watts said- 'when you get the message, hang up the phone.' If you decide to do it, you'll probably find out what I mean. There's a point where you get this very strong sense while tripping that you shouldn't do it again, or that you've reached as far as you can with it. Don't keep taking them beyond that point, that's your brain (potentially your higher self,) telling you to STOP.
