Husband sleep talking/nightmare

About an hour ago I woke up from a really scary nightmare, I had two yesterday that I had trouble trying to wake up from so with this one I tried waking him up because he'll usually hold me closer and I fall asleep better with no problems but this time he rolled over and in a low voice said "dream from hell, low to the ground, very low" and started laughing, I panicked and said "what?! What do you mean?! "

still groggy myself so he repeats himself.. "low to ground, dream from hell" "hahaha" so I sit up and said "babe, can you please wake up, you're scaring me" and he finally woke up and said "what happened?! Did you have a bad dream?!" My heart was racing so fast, I had to turn on all the lights and now I can't go back to sleep. He's sound asleep again....
