Hey Cassie

Well, seeing as it was just a dream, I wouldn't try and worry too much.
I've had friends whose bodies have reacted to traumatic dreams. For example, a friend of mine had a dream that she got stabbed in the ribs, and she woke up with blood on her shirt with no visible wound, and pain for a few days.
Personally, I would try and take a test just for ease of mind, but honestly don't worry too much.
Take care, and feel free to message me.
