When my sister and I were young, we both used to "see" and "feel" things in our house.
Often, if my Mother was not home, we'd hide because the spirit that lived in her closet would come looking for us. I saw it up close once -- within about two feet of me. I held my breath for a long, long time, so that it did not hear me in her room.
It was tall and thin and dark, but beautiful like an orchid.
When we moved from there, it was very angry, and eventually followed my sister at one point until she moved far away.
Spirits are all around us. My ex-roommate that was murdered is my guardian angel now.
Sometimes, Leigh comes to visit, if I am sad or lonely. I know that it is her, because she was one of the only people that could sweet talk my kitters.
