ok i got one from last night.
sitting on my couch, watching the voice battle rounds and eating a minsky's cheese pizza and drinking a glass of 1% milk. i was dipping my pizza which had been doused with tobasco, into a side of peppercorn ranch i ordered along with the pizza. suddenly, boo, my cat, popped his head up and looked at the window. then he ran over and jumped on the windowsill. he was very alert.
i don't know what it was but i'm guessing a pigeon landed on my windowsill and before boo could get there, he took off again. but i don't know for sure and can't prove anything.
paranormal ghost? it may have been.
