I do. Sometimes I have very vivid dreams and sometimes they are quite disturbing. Sometimes they relate to whatever I've been thinking about. I do find that I tend to have the most dreams and the most vivid dreams when I am most stressed.
No, I rarely dream. Generally, I sleep well. Occasionally, when I dream I forget what I dreamt about, so... there you go. Sometimes, when I have very good dreams they stick in my mind and I haven't forgotten them as they mean a lot to me. I think dreams have to do with a person's wellbeing and state of mind etc. I am not free of worries but generally I am quite contended and quite spiritual.
I do dream fairly often, and always in full colour! I generally have some recollection of what the dream has been about,but I only make the effort to hold the memory if it seems important, otherwise the images fade by afternoon.
Sometimes, if remembered, I dream very complicated, & 'plot twisting' dreams. Have no idea why. My brain must be 'throwing out' some guff from years' gone past!
It's rare for me to have a nightmare, but if I do, it's usually really horrendous, involving my family, or my previous work!
Whatever goes through my brain at night, I rarely remember when I wake up, & that, probably is a good thing.
We humans are of a pretty intricate make up, aren't we!
