What is going on in my head!

Last Night, I dreamt that I was in a car driving on an off ramp going towards the freeway. I was driving extremelly slow because it was very icy and snowey. I was talking to a child who was sitting next to me saying, we need to go very slow, its dangerouse, and some cars were honking at me and flying on around me, I was thinking how dumb of them. then I came up on to a huge pile up on the off ramp and I pulled over to the side, because it was all blocked off with several crashed cars. I got the child out of the car and we walked towards the freeway. It was soooo dark we couldent see much, somwhere between our car and the highway there was a dinasaur so we walked around a different rock and back towards the freeway. (hhmm? another dinasaur) anyways....this child and I walked all the way to the freeway and it got to be so dark that we coudlent see anything....but I could hear voices. I called out  are we alone or are there other people walking too? everyone ignore us. The child and I could see silluettes of other people walking down the freeway too, and they were talking to each other. The child and I were holding hands and walking down the highway. the voices of the other people had faded away and it was so dark I was so scared to move, I ddient know where we were??? I stopped and felt frightened, then all of a sudden light apeard and I saw we were standing right on the very edge of a cliff soooooo deep you couldnet see the bottom. I SCREAMED!!!  as I screamed....I woke my self up, I could even hear my self scream. It was horrifing, then about a minute later My son came in and was calling out to me..Mom  mom, and I woke up again and he was standing over me asking of I was ok? He heard me scream and it woke him up and scared him he lied down next to me for about 5 minutes and then he kissed me and said Im going back to my bed now..I Love you mom.
