Do you believe that ghosts are real? Have you ever had a paranormal experience?

I remember "dreaming" about floating above my bed when I was dozing off to sleep as a teenager. Every once in a while when I get up in the middle of the night and try to fall asleep again, I'm jolted by this vibrating sensation all throughout my body and I end up "seeing" or "dreaming" about walking around in my home. Some things in the home are the same, some are different. For example, when I try to turn on my monitor when I'm in this "dream", I might be greeted by Windows 98 instead of a more modern OS.

Some people say it's probably all in your head and I don't blame them. If this is some expanded reality (the so-called "astral plane", science is probably decades if not centuries behind in being able to explain it. Or it could be related to what others call "sleep paralysis".

Again, it's possible to chalk it up to coincidence esp since I knew he was not doing well physically but I clearly remember the night before he passed, I had a very intense nightmare of his spirit haunting me, and the next day, I got a call that he passed.
