Was it really ghost?

So I was at my granny's house which is located in a village. The house was old fashioned and its bathroom was far away from the main house. One night we had a feast with all my relatives and neighbours. After all my relatives and neighbours left, I granny aunt and my brother was left. I went to the bathroom around 1 am alone. All the lights were on and I never thought I was going to encounter something. The bathroom door made a very small gap with the wall when closed. I was on my periods. After washing my face I turned around to take towel which was hanged on the clip of the door. I clearly saw a black human figure with a white something at the middle of its forehead. I don't get easily sacred. I tried to remain calm and opened the door and looked around there was nothing. I went back and told everyone. They came but nothing was there. I dont know what it was nobody was sure also. I came back to home next day. What do you think it was?
