lol @
yo moms I didn't go as far as shrooms or black curtains

but when I was around your age 18-20 I went through a phase like this where I just went into my own world.
The result ?! The best thing that ever happened to me, it awakened me to my subconscious self and allowed me to tap into inner strengths and parts of my mind i didn't know existed. It allowed me to view the world much differently and understand and navigate it better. I was able to read and judge people better and I just 'got' it. I got everything and it's the reason I'm the man I am today.
Don't get too fukked up but I recommend you try it....
