Sherif S. Monem Theory of Dreams and Explanation

The dreams are aroused by the regions of brain that were actively stimulated the day or two days earlier, or images you have seen during the day. They come appear incoherently and  unconnected during the dream. If you were cleaning carpet or your mind busy thinking about a carpet during the day you may, have dream about carpets in strange way.

There is a logical mechanism that is active during you being awake up that makes you think rationally, however, this logical mechanism is not active during the sleep.

When you are fully awake you dismiss lot of thoughts that seem absurd. They are dismissed subconsciously and you are not aware of that process

During sleep you may dream as you are flying for example, which such thought do not occur while you are awake.

There are certain stimulation in the brain regarding events that last longer than others that may cause dreams. Although a day may be common but for strong stimulation it can be two days or longer that triggers dreams.

Note: The theory will be further expounded on.
