This happened to me back in November 2015.
I had some friends over earlier that night discussing what our plans were for over the Christmas period. My friends stayed quite late. I tided up the kitchen before going to bed as I didn't want to leave the kitchen in a mess. By the time I had finished cleaning it was nearly 3:30 am. I was wrecked and just wanted to get to bed.
I went in my bedroom and was putting some clothes away when I noticed this large white mass moving beside my wardrobe and then it went behind the curtain. I decided I would check it out, I threw the rest of the clothes I was holding on the bed and walked over near my curtain. I looked behind it but couldn't see anything. I thought it was strange but I had seen things like this before. I just shrugged it off and went back to what I was doing.
I had to go over to the other side of the room to get my phone charger, right where I saw the mass a few minutes before that. I was just about to reach for my charger when I felt someone touch my side. I freaked out and it kind of made me jump because I was the only one in the house. I turned around but I saw no one there.
A few days later I was in town doing some Christmas shopping. It was late in the evening and the shops were quiet. I went into one of the shops where I was picking up a present for my brother. I decided to take a look around first before I collected it. I went over to one of the counters browsing through the jumpers, that's when I felt something tug on my jacket. I turned around but no one was there. No one was standing near me nor was there any kids in the store. I found it strange but just brushed it off.
