Sense of Evil During Sleep

Last night TWICE while I was sleeping I had a sense of evil or major unrest. I found myself at that point beginning to pray and asking Jesus to take it away (plus pleading the blood of Jesus over my family and safety for all). At one point I got up to go to the bathroom and was more alert to be able to tell "idiot boy" (as my husband calls him) that I know the end of the story and he goes up in flames! Whoo, I was really brave!! Anyway, I just wanted to see if anyone else is experiencing these types of situations at night or even during the day. I know we are more susceptible to attack while we are asleep since the enemy knows that if he can't attack us during the day (when we are more alert) then night time is a prime time to do so.
