I'm not very superstitious or spiritual but I know a good amount about ghosts, I think. Of course they're basically spirits or apparitions of the dead.
I am quite spiritual but I am not sure what I believe about ghosts. When my mother died, I know I felt her presence and a lot of freaky stuff happened.
Oh okay, well what I find interesting is that ghosts are described so differently. Some people say they're an invisible presence but others say they're translucent and wispy.
Have many people actually SEEN these apparitions? I would love to know more.
As far as I'm concerned nobody since I don't really believe in them haha. But that's also because the existence of ghosts rides on the existence of an afterlife.
Do you believe in an afterlife? I have built my life believing that there must be more than what we can see and what exist in the physical world.
I am agnostic, meaning that there could be but there isn't enough proof for me to believe currently. There are lots of religious practices associated with ghosts, like exorcisms and funeral rites.
I have read a great deal of historical and apologetic literature based on whether or not there is a God and I came to the conclusion that there IS a designer and I believe he is God. 
See, I completely respect that but I personally don't feel that way currently. Another thing that I find confusing is there seem to only be human ghosts, but what about animals?
