Hello Brother! welcome to the nexus

glad to have another interested person in the collective consciousness!
I always say to people, dmt increases your vibrational state so that you are in closer contact, or reasier reach of the higher realms, in which a massive variety of beings, many pleasant and helpful, a few mischevious or inquisitive. I believe that each experience is like a learning tool, or a symbol of a lesson. (except maybe some peoples first ones in candyland fractal mandala world - which i think is a visualisation of rising kundalini energy up the spine, but who knows)
I would say you had a friendly encounter with a higher order being, trying to teaching you about the meaning of deja vu. Hope you learnt your lesson

-- these things happen all the time, best thing to do is realise that and calm yourself during the experience, and try to interact with them after asking for permission, you can even ask to interact with specific beings you know of or encounter, I like to keep it general. Kinda like a prayer before you blast off, "I would like to interact with all beings, my higher consciousness/godself and all guides & ancestors willing to help/teach me with xyz."
good luck and happy travels
