If you have energy then id call it an afterglow, if you dont have energy, id call it being burnt out. you can be burnt out and still be comfortable tho
after i have a complete mind trip and ooze back into soberness I always feel weary of how I'm suppose to act. Perceptional shifts can be really intense psychologically especially if you're the philosophical type because then you begin to question and question. That how I get at least, The dibbie thing sounds about right though
