Is it normal for me to feel really comfortable in a small spaces?

When I was really little, I got stuck in a toilet during a birthday for 5 hours. I screamed and cried and tried to open the door but it just didn't happen. The room was really sound proof, so I didn't realize people were trying to get me out, and I thought it was weird no one noticed, because that would mean nobody went to the toilet. Anyway, After that, I've gotten stuck in small spaces more often, but not for so long. I got stuck in elevators, one time I was in a really big public toilet and someone turned off the lights and I couldn't find my way out. Once I was stuck in a closet. What the hell right? Why does this happen so often? I got claustrophobic and I could never go into a small space again, and I would always ask someone to stand in front of the door for me instead of just locking it by myself. Years later, I was still "traumatized". Suddenly, I didn't mind. I just loved small spaces. Even more what the hell, right? I still have mixed feelings about it, and I don't know why, but it's just really weird. Why do I suddenly like small spaces?
