Weird SCARY dreams!

So last night I had a horrible dream about being apart of a massacre and having to hide from the killer... I never saw the face of the person but I remember I was very close to being found... it was also back at my old primary school & I was hiding in the school canteen! I woke up very scared & when I fell back to sleep it wouldn't let me forget that dream! Does anyone else have weird dreams like this In pregnancy.
