I definitely still dreamt during my daily smoking period, but the crazy vivid, complex dreams were a lot less common. And I'd more quickly forget lots of them. At the same time, getting high would randomly allow me to remember dreams I had at random points in my life. I'm not really sure why. I go into it a bit above but sometimes when I was really stoned I'd get hit with this surrealistic perception, and then a slap in the face, an image of a dream I had at the age of 10 that I've never remembered until that very moment. Both with dreams and random memories. That's why I think THC gave me a better long term memory.
I feel you though. I had recurring dreams through childhood. Oftentimes the exact same dream but there would be a different colored fog around it, if that makes sense. Maybe it's similar to what you describe.
