Welcome aboard
My first experience with psychedelics was very similar, at the time it just felt like a high that lasted a few hours but in reflection my life changed dramatically over the months following it, it shaped my world view dramatically.
I'd say that I learned the most about life through Psilocybin as that allowed me to get my ego out of the way and view the world from the perspective of a new born again, it was very insightful to be able to get back in touch with that knowledge. From there I tested out what i'd learned with DMT and found it to be accurate.
Looking forward to hearing about your experiences. As i'm sure you'll come to know, everyone's experience is unique but somehow similar and from my own research i've found that the entities encountered seem to fit a profile that suggests them to be real beings that exist in higher dimensional planes, not that I want to influence your thoughts on that as it is very much up for debate.
Welcome!
