There is no bigfoot/sasquatch/yeti.
There are no space alien visitors.
There are no reptilian beings. No matter how much you don't like a person, they are not reptilian.
Anyone that can talk to the dead is either a liar or should be institutionalized.
You can't change your "frequency".
Nobody, ever, was visited by a ghost.
There are no black snakes under your bed.

Now, take off the tinfoil and go to bed. I'll leave the closet light on for you so you're not scared.
