well. imo and from the experiences i have had in the past, these realizations do not happen to everyone and they do not happen in every trip.
im quite introvert when i take psychedelics and i prefer to take them and focus on some task that i like to do (drawing, music, etc). i dont normally tend to think philosophically when im on them.
nevertheless, the first time i took acid it did change the way i looked at things and perceived the world. not necessarily in a delusional way. i didnt become a fucking hippie or something like that.
it might be different for you. my suggestion is, if you want to try, get informed and make sure you feel confident and happy to be tripping for a long period of time.
