I often have the same dream every night, and when I wake up it totally freaks me out because its the same events in my dream (or I believe them to be once I awaken, whatever the case, its freaky) and they seem to have little meaning or relevence. Yet, I have the dream over and over. That might be deja vu, but I had never thought of it that way. And I couldn't tell ya if something or someone is trying to tell me something, or if my brain just tends to skip at night and its really just an annoyance.
I also notice this dream to happen after Ive smoked (which is almost every night, if not every night.) so Ive often blamed cannabis for this dream being stuck on repeat.

What you're describing however sounds more like repressed memory, which I dont think is what deja vu really is. I could be wrong. I probably am, lol. See if you're insurance covers therapy, and delve deeper, cuz it really does sound more like repressed memory from trauma than anything else. Or you smoke much too much cannabis, lol.
