When I was still in high school, & I saw outside our window someone wearing a white shirt, the figure was black (arms & face). I thought it was my cousin trying to scare me (he was staying with us that time). I immediately went out to the window side, there were tall plants near the window, & I checked that the space was too narrow na hindi kasya tao (& walang shirt nakasampay dun hehe). I also realized na my cousin wasn't at home yet.
I have 2 different friends (who don't know each other) said that there are ghosts in our house. My sister's ex boyfriend was a spirit questor. He also confirmed that there indeed ghosts in our house. But he also said that there are ghosts everywhere naman, even in the streets, in the mall, etc.
