Nightmares when too hot?

Does anybody ever have nightmares when they are too warm while taking naps? If I take a nap and I have too many blankets or layers on then i am lot more likely to wake up really hot, heart racing, freaked out over a nightmare i just had that caused me to wake uo suddenly. Just now, I was in a state between sleep and awake and i coukd hear my boyfriend talking to his friends on the computer but I was also seeing and experiencing things from my dream. it was a terribke place to be because i couldnt talk or wake up and i was in pain and over stimulated. The only reason i woke uo was because my boyfriend yelled a question at me and it helped me escape the torture. I just wondered if any of you experience something similar with naps, being too hot, and weird nightmares.
