I prefer solo tripping as well. I found in the past that at the heat of intensity among a group of friends we'd always have different ideas of things we wanted to do and at sometimes the effort required to process and make decisions just wasnt there and it would spin things negatively for me, just having to think.. I know that sounds weird, maybe it is, I'm not sure.
I enjoy tripping within the viscinity of my home, it adds to the level of comfort, and being able to do things like jump in the shower 4 times if it feels right sits well with me. I can lay down and zone out, take my shirt off if im hot, put 5 sweaters on if im cold, I can come on the net, I can go out and lay in a field and have phantom dogs attack me, nothing inhibits what I want to do and for me this is a large part of being able to enjoy a trip.. I've had some rough moments even in these scenarios, I'd hate to have had those happen in the middle of a concert or whatever.. just me though. The worst is when you're tripping with someone and they start having a bad time or freaking out and you just can't deal with it and would rather wish they werent there at all because that would be the easiest solution to the problem! lol. I look to moments I've had myself where I feel like my heart is racing too fast or my bp is too high or something just feels wrong - I'm able to work through those kinds of things, but not everyone is, and them being freaked out would lead me to get messed up too when Im not thinking clearly.. I dont know, its hard to put it.. sometimes everything around you is so overwhelming and having to deal with the task of something, especially someone having a bad time.. is just not enjoyable in the slightest and totally bums me out and adds bad vibes that can shift the entire course of a trip
Low dose Im fine around others but I tend to like to push things and with that comes sides, not all negative, just not necessarily comfortable in certain environments.
