Unknown Experience

When I was young I had this very weird experience. It is hard to describe it or more exactly what to call it. Well I remember when I was very young I don't remember what age I was but I remember I was very young. My family went to this person's house. He had many crosses and prayer books. He sells crosses, books, rosaries, etc.

Well my parents went inside his house and I was heading after them. My brother and sister were behind me. Well right when I was going to enter the man's house I had my foot on the doorstep (you know the metal thing that is underneath the door when you walk into a room? Well that is what I am talking about). When I had my foot there I just suddenly felt that I was pushed back. The weird thing is that I felt like energy or a sense of something going through me and pushing me back. It makes me feel very dizzy.

So when that happened I literally stepped back like something just pushed me. I was shocked because I was not expecting that. My family looked at me and was asking if I was alright. I told them yes to not worry them. So we were inside the man's house waiting because my parents were talking to him. My sister, brother, and I just stood there looking bored. I was thinking of what happened to me. My parents bought some prayer books and we left.

Throughout the years I keep having that same experience whenever I go to people houses. Like my aunt's and uncle's house and to other places. Throughout those years I was very confused and was afraid to tell my parents. I was thinking that something was wrong with me. I was 17 when I told my family and they asked me why I did not say anything to them. I told them I did not want them to worry. They told me that they did not know what it was that I was experiencing. Now I am 19 and it happens from time to time. Does anyone know anything about this?
