Vengeful spirits finally moving on
Last night, I dreamt that I was in a haunted house with my parents and our dog. The spirits kept giving us those tasks, sort of like tests, and if we failed them, we'd die. When we finally got to the last task (singing a good song, preferably R&B... yeah, wtf?), some people who were helping the spirits decided that enough was enough and decided to let us go. Then, as we were leaving the house, those people suddenly became the spirits and they thanked me. They shook my hand and said they were finally able to move on. The last thing I remember is feeling a cold hand holding my hand, someone saying "you still don't believe we're real, do you?" and someone whispering in my ear (no idea what it was, it just felt like they were softly blowing air in my ear).
Now, I'm silly and afraid of the dark and I have this weird thing that I don't really believe spirits, but I'm afraid of them. I'm absolutely sure that, once you die, you're dead, but for some reason, I'm always afraid of seeing something. It makes no sense and I'm aware of it, but that's the best way I can describe it and I'm sure that this indecision played a huge part in the dream.
Anyway, does anyone know how to interpret my dream?
