I guess you can call this a ghost story, actually I dont know what to call this experience, theres actually two instances that this has happened. The first one happened about a month ago, my mom was home and started doing her morning routine of straightening the house. I like to sleep in so when 10 AM came around my mom wasnt surprised that I wasnt up and about. Well I'm a college student and I go to class everyday from 11-3 except for Wednesday's when I have a 8 AM Lab and I work afternoons from 4-8, so you can see that Wednesdays are not my best days. It just so happen that it was Wednesday so when I got home that evening I was just about to pass out. My mom asked me "why are you so tired?" and I looked at her in disgust because she knows how much I hated Wednesdays and I reminded her of my 8 AM lab. She looked at me kinda funny and said "but you were here this morning, were you late?" I had no clue what she was talking about. She then continued to say that she heard me in my room getting ready and that she even spoke to me. Now there was absolutely now way I was home, I have to leave a half hour before my first class which would have been 7:30 AM and everyone was still asleep. My mom to this day swears that I was there. The second occurance happened a week after that. On Sunday mornings I go to a youth group and Im usually out all day. On this particular Sunday I had to leave extra early becasue I was driving by myself, so I left the house around 9 AM. My dad was already up and getting ready to have breakfast. When I got home that night my dad asked me "Hey did you forget something this morning and come back to the house?" I answered "No, why?" He then had this confused look on his face and he told me that he was having breakfast and he saw me open the front door walk in, go through the living room and walked right back out. He said it must have happened 45 minutes after I left, and I know it wasnt me because I have to drive about an hour to get to my youth group so even if I did forget something I'd be t o lazy to turn around. I cant think of any other explaination except for they might have been imagining. Can you explain it?
