Few days before ramzan I read some research so I like to share.
We dream all most whole night, i think, most of them senseless weird stuff. Many theories but no one knows certainly know why.
Lucky us, by the morning we forget all most all of it. UNLESS we are waken in middle of the night.
When they did this experiment, they wake up subjects with intervals of 2-3-5 hrs(some thing like that)
Subjects then remember what they were seeing in dream, which other wise they would have forgotten.
Now in ramzan, we have our sleep disturbed. I almost every day, have the strangest-est-est dream when I wake up with alarm at sehry.
We also know dreams are connected with uneasiness of body as well. So do the math.
Not usual food + waken up in the middle + sleeping light after = we get access to worst dreams.
