well i've had a few, but one that is easy to remember is, whem my mom and i were living with my aunt and uncle, i was accually at the house alone, and had come upstairs from the basement. for some reason i just had to look out one of the back doors, when i did, i seen what looked like a farm boy, dressed in overalls and a white t-shirt. i had to look 3 times, the 3rd time he was gone, but the first 2 times he was there but see through.
