Dreaming of Devil? -scared to death!?

I had a dream last night that I was john locke from Lost, and a man gave me a sack of potatos and I was so happy to take them to the devil and ran through the woods trying to find him. Demons knew I was coming so they killed my (locke's) son and when I got there I was in the basement of a building and I shut the demons in a dryer and melted them. Then the devil came down from an air vent and ate all my potatoes and with a ritual made me a servant of his. I asked him if I could go outside and he said no. And I was very upset and that's when I woke up.... I'm scared to death and so worried because I made a deal with the devil in the dream and I wasn't even myself! HELP! I don't know what to think and I'm so freaked out!
