Anyway, I haven't had any experiences or encounters regarding Ghosts or Spirits, but I'm pretty open to the idea that they exist. As for UFOs, my brother claims that he's seen two. I definitely think that there's other life out there, but I don't really know if I believe in these FLYING SAUCER stories.
I don't know if this counts, but one unexplained thing that I'm very interested in is the Loch Ness Monster and Bigfoot. Basically just cryptozoology in general. I've done lots of research on the matter, and it just fascinates me that there could still be animals out there that we have yet to discover. People say space is the final frontier, but there's actually quite a bit of Earth that has yet to be extensively explored and studied!
