I know what you mean, I went through a couple months a while back where I'd be having really horrible dreams, but it was less completely weird and trippy and more like seeing people in dreams who I badly regret how I left things with them, miss, ex's and the like, really really uber depressing dreams to the point I was waking up and feeling incredibly unhappy for hours afterwards, I'd never have a dream so massively effect my mood for so long.
A nightmare, running away from something, falling, whatever you wake up feel a bit weird, shake it off, forget about the dream fairly quickly and never long term mood effecting.
I have no idea why, I do suffer from depression but I hadn't actually been anywhere near my worst at that point.
I sleep incredibly badly in general, can't ever get into a pattern of sleep, same time, same time waking up, sometimes I'll go to bed not tired, fall asleep very quickly, other times I'll go to bed, shattered, and end up desparately trying to sleep for hours.
Don't bother with a hypnotherapist(not tried one) because in theory, they want you to hide something your subconcious mind is trying to tell you, see a proper therapist, have them poke around in your head(metaphorically) and see if they can find the reason you're having such weird dreams, actually fix the problem rather than hide from it. Not that I do that, I hide from problems like most people, giving advice is easier than taking it though
