I think I've already posted these stories in another thread, but what the heck? I'll do it again.
I have had two encounters. One happened at my house. I think I should add something first. My family came from Ireland in the early 1900's and built my grandma's house (which is where my second story will take place). When my dad married he moved maybe a half a mile away and built his house. I do know that the house was built on an area where Native Americans used to live (evidence by the arrowheads), so maybe that caused what I saw?
Anyway, I had gone home a few years ago. My house is set up around a long hallway. My room and my mother's is at the end, and at the other is the living room and family room. I had gone to the bathroom to take out my contacts. I was looking in the mirror when I saw a woman in white walk down the dark hallway towards the living room. At the time I thought it was my mom. I remembered that I needed to talk to her, so I followed "her". I checked out the rest of the house, but everything was dark and she was no where. Then, I went to my mom's room. Of course she was in bed fast asleep! I know I saw something because I could see the details of the dress.
What was even freakier is what happened last Thanksgiving. I had kind of forgotten my own story, especially since I knew what I saw was a kind spirit. My bf had come home with me for the holiday, and when's he's at my house he sleeps in the living room. One night he asked me if my mom would try to scare him as a trick. It turns out he was laying awake (and in the dark) in the living room and turned towards the foyer area. He saw what he thought was my mom, who was standing there staring at him. He called out her name but heard no response. Then, what he saw vanished. The odd thing is that I never told him about what I saw, and we both saw this spirit around the same area. To this day I still freak out a bit when I'm at home!
Ok, next story about my grandparent's house.

My grandfather passed away when I was very young, but I do remember that they cared for him at home. My grandmother ended up moving out the house when I was a sophomore in high school. (She broke her hip and couldn't stay by herself in the huge house.) Well, in high school I had small parties down at the house. One night I had my two best friends stay over. One friend wanted to go to sleep, so she left where we were and went to another part of the house. My friend and I stayed in family room and was up late talking and goofing around. We kept the lights off so our friend wouldn't be kept awake, so we were sitting basically in total darkness. Now this room has two huge windows in it. Well, suddenly we both saw this huge, circular light shining through one of the windows. We live in the country, so we would've heard a car come by. So it wasn't a headlight. Besides, the light was maybe a foot in diameter and was shining brightly enough to eluminate the room. To add to it, our once asleep friend came running into the room after she heard our shrieks. She couldn't see the light! I sat there pointing at it, but she never saw it. She even went outside to check, and there was nothing there. This light stayed where it was for maybe 3 minutes. Definitely odd. I have always thought that house was haunted. It just doesn't feel right. To this day I never go down there alone! Dad used to tell me stories of house a man was hung on the property, but I think he's just teasing...I hope!
