The Push And Touch

I was taking laundry to the basement and when I opened the basement door I seen a dark shadow at the bottom of the steps and it went towards the washer and dryer. I continued doing what I was doing and as I was putting laundry in the washer I had the sensation that someone was watching me. I finished putting the laundry in and went up the steps. As I was walking up the steps I was pushed and touched on the neck(left side). No marks were left,but it was semi forceful feeling.
