hey chakra fairy! welcome and glad to have you here!
This sounds like an exciting moment for you! I'm curious whether you have experienced any other psychedelics, as you only state mushrooms! There are so many psychedelic plants and fungi,
As for new tripper thoughts, I can personally recommend: take it easy! start low, go slow
be gentle with yourself ~
I have had most of experiences outside just me myself and nature. I like that sort of setting. If you feel a lot of emotions, or you think some are going to be coming up, remember that you can sit and simply let the ease of that posture slow down your heartrate and thus also, mind
Simply sitting criss-cross-applesauce for 30 minutes or even 2 hours can build up a lot of clarity-momentum.
It really depends on what you are going for! I'm a zen person so that has been with me in trips. xD
Maybe a few random things:
-bathroom options nearby (you might not want to have to walk very far just to go the bathroom if you sense of space and time are be-ing expanded xD)
-after the trip, you may be exploring some new feelings/emotions. It can be nice to have a way to explore these feelings. The seismic waves of the trip still reverberate after the trip. Again, I can recommend sitting for this as well. For instance I had a gorgeous, pure serenity, very easy LSD trip the other day, and AFTER the trip, I was feeling some very difficult feelings. These feelings can be completely new relationships to life as you know it.
I guess sometimes there are as many ways to trip as there are people tripping! xD this is up to you to explore, as the person you are who you bring with you, and the experience you design is somewhat of your own craft
