I understand how you feel about the no-lesson thing. I've felt that way too in the beginning but I've come to find that each dmt trip lingers with me for much longer than is obvious. sometimes I will notice its effects in very subtle ways days after... things become clear or an understanding of certain aspects of the experience unravelling into my conscious self in a very quiet fashion. I would not dismiss the value of vaporized spice just yet. Try to pay attention to very fine sensitivities you possess.

I see it as a making contact with parts of myself, previously unknown to me. The contact seems brief, but I am building bridges into those areas of the self. Maybe only frail tendrils at first, but enough for a miniscule communication to take place. And the more we delve into dmt, the more these tendrils can become canals or portals to our inner worlds, for us to explore deeper and deeper...

It's just an image and doesn't have to hold true, but it describes the feeling I have sometimes.
