On shrooms, I always have a phase were I emotionally rethink the past about humans I met in life and wonder how I could be such a cold-faced guy in that situation, while a simple smile or some nice words e.g. could have eased the whole situation for anybody involved.
I often have also the feel just to go out and run around near a canal with some nature, grass, trees etc. to feel the freedom we have in our life, but often don't act on it.
Also, the days after, I feel more connected to the world itself. Casually at work I feel like a zombie, 60 % awake, while still maintaing complex situations in a fast manner (part time job of driving pallets like the other 20 people on small gate ways).
Mostly, I laugh my ass off on trips, but they always contain some very serious moments too. Once I ended up for hours google-imaging pictures of shellshocked soldiers, because I feel a deep relation to them, their whole face expression and body language. Probably because of my own depressive mood, which always blends through.
During a trip, I always write down lots of ideas, because everything makes so much sense then, you experience the value of life and I am so motivated to improve my life with clear plans. But when the trip calms down, I just become detached again. So I have those .txt-files with really good ideas which could improve my poor mans life extraordinary, but for some reason I often just don't care nonetheless.
Looking in a mirror and focusing on yourself, you see all the faces you have, the funny ones, the sad ones, the nice ones, the ugly ones.
Mushrooms evolved my Co-Pilot function, Extraverted iNtuition. As we all should know, Ne is very important for a balanced INTP to become more happy with life. Mushrooms definitly can help.
Drugs are tools, use them wisely to improve yourself.
You can buy Growboxes from dutch internet shops (implying you life in Europe, USA is forbidden to import them IIRC) like Zamnesia or Azarius. You can also start growing mushrooms yourself, it is a very nice hobby, which is teaching you alot.
My choice is always the Golden Teacher strain, put like 1 to 1.5g dry in tea for a small trip (e.g. face morphing, but not on Mars), let them soak a while, chew them nicely and then eat (and drink tea to end of course). Before I had Cubensis B+, but they are crap compared to Golden Teacher.
Maybe start with a bit less mushrooms to get some feeling for your brain on psilocybin first, because some people are just way more sensitive to it and e.g. 1 gram might go much stronger than expected. There are too many unknown variables (plants + digestion + brain).
