Today, during English class i fell asleep and dreamed I was in English class. then I woke up, and i was in English class, and then I woke up again. etc. etc. It happens to me every so often... I will dream myself waking up multiple times, and each layer is so realistic... Problem is, I don't remember falling asleep... meaning, i felt tired in my dream and didn't noticed anything had changed until something weird happened, and then I would wake up in another dream that was almost the same... When I finally woke up for real, i was shivering and felt extremely cold, the room was 75 F, and I was wearing a jacket. Is this normal? It happens to me often...
