"Some other dizziness triggers i forgot to mention:
I do feel dizzy/lightheaded for a few moments when i'm lying down and then i stand up. Or sitting down and stand up too.

I also feel dizzy if my head turns/moves quickly sometimes. (like in the shower or brushing my teeth)

And sometimes when i'm lying down on my back, and i'm looking in a perticular direction, my head feels weird. (little nauseous) "

These are movement induced issues. You move and it triggers a dizzy response. The getting up from laying down or sitting can be blood pressure oriented or inner ear. The other movements suggest possibly inner ear/ Epley treatable issues.
