Thread: What do you call a dream that continues after you wake up?

I once had a dream that I saw a man continuously falling in a bottomless pit. His screams were so unbearable to listen to (like fingernails on a chalkboard kind of terror) that I couldn't stand it. I realized it was Lucifer (in the future) when reading the account in Revelations about Lucifer being cast into a bottomless pit for 1000 years.

What is weird is that I woke up from this unpleasant dream and walked into another room to try to get away from the thing I just saw (to calm down). I was completely awake and had the lights on in another room. But, to my amazement I was still seeing and audibly hearing this vision. The screaming of Lucifer's torment was audible in my ears. I finally prayed to God to take this away and it stopped. Note: I had no sympathy for Lucifer and his torment. It was just an unpleasant sight and thing to hear. Very strange experience. What would you call this? This was not a drug induced hallucination (I don't do drugs or even drink alcohol).
