I just woke up in the middle of the night having a panic attack (i think)?

Well i was dreaming of this girl jumping on her trampoline and a van comes through her backyard and runs over the trampoline. They mom freaks out and is shaking around trying to run to her house. Then all the sudden i think my heart starts racing and i basically panic because i realize my body is asleep and my brain is awake and i force myself awake and i was breathing heavily and it was so weird.. Help diagnose this!
