So last night I was trying to get to sleep, I think I had a bad dream of something because the next thing I remember is I was on my side instead of my back and I suddenly saw a image of snakes in my head. I freaked out and then realised I couldn’t remember what day or time it was. A few moments later I remembered and I checked the time and only half an hour had past since I got into bed. I was really freaked out I lost my memory’s is this normal ?
