After a series of studies, scientists have found that people see per night, on average, 4-5 dreams. This is due to the shift cycles, each of which includes a fast and slow phase of sleep. The second phase is accompanied by muscle contractions, eye movements, and sometimes even sounds and slurred speech. Using EEG you can see changes in brain activity in these moments. If you care to Wake a man when he is in the REM phase of sleep, he probably remembers that he saw a dream.
If a person thinks that he saw no dreams, probably means that he just don't remember them. This can happen due to poor conditions for sleep: unusual sounds, too high or too low room temperature, unfamiliar or unpleasant situation, etc. When a person is constantly waking up due to external stimuli, it is likely that any dreams he won't remember.
Other, much more common in our time, the reason is insufficient sleep duration and unsuitable conditions for awakening. When people are too tired at work or at school, go to bed after midnight, Wake up at six in the morning and immediately ran to wash and dress, they sometimes think they fall asleep like drowning in black water. Brain is too exhausted from constant stress, the body is tired from lack of sleep, and the dreams are forgotten instantly. Moreover, even if you had a vivid dream and you remember it immediately after waking up, thoughts about the upcoming day can crowd out all the memories, and after a few minutes you find that any sleep you have not seen.
Learn to Wake up properly. Change the time of waking up to the alarm after you have had another 10-15 minutes to lie in bed. Change the ringtone of alarm clock, so she pulled you out of sleep and helped to slowly Wake up. Immediately after waking up, block all thoughts about the upcoming day and about what you need to do right now. Try to remember your dream. If you fail the first time – do not worry. Over time, these exercises will bear fruit and you will be easier to remember dreams.
