Your story a bit unbelievable
Ghost exists but you hardly see them in human form ... I means you only able to see them in white or black shadow ...

vendetta87 we can ask TS to join us for ghost hunting ??

Should travel to more different country to see different creatures and ghosts type! The most geli is the red faced demon from insidious.  Do any of look like  the red faced demon?

it really affects me at sometimes. the beach is a no no. but pool is ok. I still drive at night, but not when using unfamiliar lonely roads.
never watched insidious. but there's so much kinds of "monsters" or "creatures" out there,there;s bound to be one resembling those from the movies.
out of the three movie you stated, I've only watched the sixth sense. and that movie is sort of accurate.

there's something like that. appeared from behind me when I was in a hotel. to be honest there's plenty that sort of look like that. even scarier ones.
