This likely means that you're highly connected to your subconscious, or that you're highly creative/in tune with the world (not that those necessarily mean the same thing but they go together well). Maybe there's something disturbing in your past? Honestly, who knows (except maybe a psychic if you follow that). But I share your vivid dream thing, though for me they're never scary even if they are.

If it's giving you a lot of issues, seek help. That's the best I can give you sweetie, sorry.

Oh yeah, and welcome to PC!
