I think that spirits are real, but you cant see them. Ghosts you can supposedly see are probably your imagination,a hallucination, or daydreaming. It could also be actual dreaming, and it just seems real.
Yeah i believe in ghosts. Their most common form is a type of mist, it makes you freezeing even if its like 90 outside, Ghosts aren't just in human form. I also believe the ghosts of gettysburg are real.
