Is this normal?

When I was about 1 or 2 years old i was at my trailer with my babysitter while my parents were at work and my siblings were at school and the trailer caught on fire. Now I have dreams that I am caught in fires and where I live catches fire and stuff like that and I wake up in a cold sweat and crying. Is that normal or should I get it checked out? But the weird thing is that I dont remember anything about it.
