Hey JiayoJames,
I've had that happen to me a couple of times. I think it means your does might have been a bit too high, but then it could be a number of factors that play a role. Quite frankly, we don't have the data to know for sure what causes what kind of experience, if they can be predicted or caused at all. I suppose from what you write you feel good about it though, so take it for what it's worth. dmt works in mysterious ways. You still might find some value in the whole thing, you might remember things in the days to come or you may crystalize this feeling inside of you and let it grow into... something... test out the newness of the sensations...
try a lower dose next time and see what happens.
cheers
Enoon
