I have these memories of feelings, sometimes they affect my dreams?

When I was little, I would get up really early and watch Sailor Moon. It was on at 6 or 7, so it was still dark out. Idk why, but the darkness kinda scared me. But I loved the show too much to let it bother me. I remember there was a a scary episode about darkness and it kinda freaked me out. It was a weird emotion. I think I felt it in a few dreams. But I was like 4, so whatever. I've recently been watching Vampire Knight and I've developed an addiction to Pocky, and I've been getting that feeling again. It's like a frightened hopelessness. I've had dreams where I'm trapped in another world filled with darkness, depression, blood, stained gl, vampires, roses, apocalypses... I don't think there's any link to my childhood, but it's the same feeling. It's beautiful... it's a delicious insanity I'd love to get lost in. Do you have a similar feeling? Or a feeling that doesn't quite make sense to you? Can you help me understand these dreams? It's unreal but familiar, difficult to explain.
