Just reading this post sound very similar to experiences I have had.  No mushrooms or anything like that.  When I first started what I would call interpreting my reality differently I was presented with what I might call God, or maybe the Devil, whatever it was was beyond me.  During this time period I had extreme highs and extreme lows.  I was going crazy and at the same time I wasn't.  It was as if my mind had been opened up and I was running around in the new space like a chicken with its head cut off not knowing what to make of it.  Some experience were like synchronicity but instead of a something that could be chalked up as a coincidence, I feel there was literally a communication between my thoughts and the world.  One of the most profound and mind blowing things that happened to me was the TV talking to me.  Which obviously sounds stupid and crazy and your on drugs.  However, when I first told my self oh shit the tv is talking to me I then told myself you are crazy lets be logical here and immediately the TV had a response that said I wasn't.  This type of thing happens to me all of the time now.  For example just the other day I was talking to whatever is out there to see if I could have a sign, (despite numerous past confirmations)  I tried to listen to the first thing that came to my mind which for whatever reason was the word count.  Instead of trying to interpret it like I usually would I just started counting.  1...then i lifted my vision which landed on the side of the building i was walking towards right where there was a number 2.  not a bunch of numbers and i saw a 2.  a single 2 written on some plastic thing coming out of the building.  I looked around and there were no other numbers.  This is just something recent I can remember and not as out there as some of my other experiences which include the sounds from outside and pipes in the wall banging loud and creating a perfect rythm together slowly morphing into a beautiful song that frankly scared the shit out of me.  I guess what I am trying to say is there is definitely something out there or in my mind maybe that transcends our laws of reality.  and that by seeking with the right intentions will reveal itself as you are ready.  The experiences I have had me think things like I have superpowers, my friend is jesus and i have been chosen to spread his love, i am about to die and go to hell, most of the time I am overwhelemd and confused so I tend to go back to "regular" thinking.  But if you simply start to let your mind experiment with the possibilities of the infinite you might find something that you will believe 100% but even your best friend would think you are crazy or just brush it off like nothing happened.  SOMETHING IS HAPPENING.  I am not sure what but I can't continously deny the most amazing and real experiences I have had because they don't fit into what I thought before they happened.  Sorry for typos even though theres spellcheck.
