This didn't happen to me but it happen to my aunt and the little lady she takes care of. The little lady is sick. She has a mental disorder. She has the mind of a 5 year old and she has been like that her whole life, she's about 46 years old right now and my aunt it kind of her nurse and takes care of her.
Well one night they were all sound asleep. They were the only ones in the house. And my aunt woke up in the middle of the night because she had to pee. And this is in Mexico by the way and over there some bathrooms are outside waaay in the back of the gigantic coral or backyard like an out house. And at night these enormous yards look terrifying and pitch black dark! So she really had to go pee she tried to hold it in because she was scared to go all the way out there all by herself just too pee but she just couldn't hold it. So she woke up the little lady and kindly ask her if she could accompany her to the bathroom, because the little lady gets very grumpy when you wake her up, just like a 5 year old.
The little lady was like "Ok I go with you" [ She speaks like a little kid] and she just got up and put her little slippers on and out they both went. My aunt was really scared to go out there but the little lady dose not really know anything about danger or ghost or monsters, she doesn't know any better so she was just all calmly with her not even a bit scared.
So when they reached the bathroom my aunt went in and the little lady sat outside the out house on a little log waiting for her. My aunt was inside peeing and trying to make conversation with the little lady so she knew she was still out there and didn't leave her to go back to sleep. When all of a sudden my aunt hears the little lady shout out "Aye! Get out of my house! Get out! Get out!" My aunt freaked! And ask her what's going on!?! And the little lady was very mad telling her that there is someone in the house and that she wanted to go kick them. My aunt was like no! Stay here don't go anywhere! Don't leave me here! [All this while she was peeing] The little lady just kept saying the whole time "Look he's inside the house! Tell him to leave!" My aunt got out the bathroom as fast as she could but when she went out there was no one there, she asked the little lady where he was and she took her to the exact spot she saw him and said "He was walking here! But I scared him away when I yelled!" all proud. Now the thing about this is that the little lady's mental disorder does not give her the ability to just make up a lie she wouldn't know that her aunt was scared and it would be fun to scare her by telling her there was someone there, she just doesn't have that ability. She can't make things up.
So whatever she said she saw was most like there. My aunt says that she thinks it's the spirit of her grandfather, because he has been seen there a few times.
