I believe there are spirits or ghosts roaming the earth. However, what exactly are they? I can't see them being dead people, as the Bible clearly states that we all sleep after death until reawakened by God.

Hence, the things we call spirits or ghosts must be from another source. Some believe they could be demons. This could be true in some cases, though I don't feel we can label them all as that. They appear to be another life form and maybe as protection to themselves, they can change their form into human or even animal.

I think there needs to be a lot more research done on this subject, before we can define exactly what ghosts are. I haven't seen one up close so far and I am quite content to stay that way. There are just things out there that we really have no idea of what they are.

Eventually, we may discover more answers. Only time will tell, I suppose.
