Document Summary

When do we dream? dreams occur throughout the sleep cycle: tend to dream more as morning approaches. Rem dreams: have a vivid, story like quality, most dreaming occurs during this stage. Most nightmares also occur during rem sleep. Slow-wave (deep) sleep: brief often a single vision/feeling/image. Night terrors occur during this stage very intense panic, coupled with physiological response. More like a feeling or a single image: e. g. being crushed under an oppressive weight. Most dreams are actually really boring: may be slightly illogical or implausible, but typically are still sensible, realistic words familiar settings family, friends, and colleagues, just like real life, we tend to remember the more exciting things. 30-50% of people have had a dream of flying. But flying dreams are not at all common (less than 0. 1%) Doesn"t mean we solved the problem while dreaming. When we are awake, cerebral cortex makes sense of neural activation -> meaningful perception.
