Hey everybody

I have dreamt in black and white my entire life. There isn't one dream that i've remembered that contained any bright colours.
If i see any colours in my dream they have a very low brightness, but most of the time all of my dreams are just black and white.
My dream recall isn't very good, i remember like 5 dreams a week maybe but not the whole dream but just parts and i can cover
up the context of the dream.

Does anybody know why this is ?

Is this permanent and will i never experience colorfull vivid dreams ?

Any solutions on how to fix this ?

P.S. i am depressed and have been depressed for 7 years, but i've had black and white dreams long before i became depressed
