Neat story.
Mine's not halloween related, but here goes.
8-9 years ago I was awakened in the middle of the night by Milo, our fixed, female indoor cat. She was ticked off - or scared, I don't know which.
I woke up (she'd never done that before, or after by the way). I heard what sounded like a table being drug across a wood floor. I got up to investigate. Noticed my daughter had come downstairs at some point in the night and was sleeping in my bed.
Walked out of the bedroom, and there's Milo, right outside my bedroom door. No windows near her - and she's just meowing like a mad cat.
I checked the main floor, then the garage. Nothing. Went upstairs.....nothing.
Went back to bed, and Milo followed me. I didn't have a clue what had happened....just chalked it up to "it was nothing".
Next morning, taking my daughter to school she made the comment: "Dad, I know it was nothing. But last night I got in your bed. I woke up, and you weren't there, but I saw a guy in the hall looking at me. He didn't have legs. He was wearing a jersey with the number 00 on it. When he saw me looking at him, he disappeared."
My blood chilled and the hair on my arms stood up.
The cat saw something.
I heard something.
And my daughter saw something. (and no, it wasn't me. I don't own a jersey with 00 on it, I have legs, and I don't just disappear.)
