This happened a few years ago when I went to Myrtle Beach for my birthday with my parents. As a gift, I even got my own condo for the week.
One morning we were getting ready to hit every mini golf course that appealed to us. I had gone into my parents condo to say good morning and was now back in my master bath performing my morning toilette. I was just finishing my teeth when I saw my mother walk past the bathroom door. I thought she was trying to pull a prank on me with the old "pop out from behind the corner" gag and didn't know I'd seen her. I finished my teeth quietly, preparing to have her prank backfire on her. I tiptoed to the door to my bedroom (it had a door to the hallway and a door into my bedroom). I flung it open and the room was empty. I walked all around but she wasn't there. Note this was right by the front door of the condo; however the door is so heavy that it is physically impossible to open and close it silently. I went into their condo and asked my mom what she had wanted, on the off chance that maybe she had. She didn't know what I was talking about. I told her that I had seen her walk past my bathroom. She thought I was going nuts and logically so. I know for a fact that I wasn't imagining things because I had seen her as plain as the nose on my face. I was freaked out. Naturally Mom doesn't believe me and I don't dare talk to her about it. However, this isn't my only experience with the paranormal, I have a few others but on a lesser scale, but that's for another time.
