psychics, OMG, I hate the tv ones, they prey on bereaved people, they say youve got a piece of jewellry or you are moving soon - seriously and the person in the audience nods and says , yes thats my Herbert, thats him........aye
I don't believe most of the various sightings. I can't completely doubt all ghosts, but I doubt most. I can't doubt aliens, but most sightings are attention hounds looking to get noticed.
Monster sightings.... I believe most are mistaken identification. But there are species being discovered that we never witnessed, yet have existed for a very long time.
Bigfoot? Nah. Chupacabra? Dogs with leprosy or something. Psychic Mediums? Frauds.
