Terrifying dream- unable to snap out of it.

Today I laid down with my daughter while she was napping and I dozed off. I started dreaming that I was in the car driving with my daughter in the back. I slowly started to feel like I was drugged. I was still driving mind you and I started to get very scared because I felt like I didn't have control of my body. I was freaking out that I was driving with my daughter in the back feeling this way but I couldn't stop. I didn't know what to do in the dream so I was just trying to get home. I pulled up to a stop light where people were crossing the street and I slammed on my brakes. I realized in a daze that I hit someone as a family was crossing in front of me. They ran to my driver side door. I was trying to open the door to see if she was okay and say I'm sorry but my whole body was just limp. I felt like I was nodding off. I reached for the door to open it but I couldn't get it open or say anything and I could see how angry the faces were on the other side.

At this point I woke up and as I opened my eyes I still felt drugged! I started freaking out worrying if something I ate was causing like a freaky allergic reaction or something. My head felt heavy like in the dream and like everything was spinning... a few minutes later the feeling went away as I became more awake/ aware but it was so terrifying!! Something like that has never happened to me before. Has this happened to anyone? I was too afraid to try to go back to sleep.
