Dream

According to my theory, first of all consider an electromagnetic field parallel to the x-axis around our head, such that if anybody standing in front of us view it, he may see it to be at a position of our forehead  going round towards back portion of our head and thus making a complete circle around our head.

According to our mathematics X-Axis is considered to be "REAL AXIS" and Y-Axis to be "IMAGINARY AXIS".
In "Hindu Religion" we say "Sita-Ram", here Sita is goddess and Ram God; Sita represents mother and Ram represents father. Mother is said to be real and father an imagination. If we match the system of writing the coordinates (x,y) and saying "Sita-Ram" we may find that: x i.e. Sita is real and y i.e. Ram is imagination.
Hence, when we are busy in our daily routines i.e. standing, sitting, playing etc.. we are having our electromagnetic field parallel to X-Axis viz we feel everything real, since it is parallel along real axis. Similarly, when we lay down to sleep, we are having our electromagnetic field parallel to Y-Axis viz we get lost in an imaginary world, since it is parallel along an imaginary axis.

I agree that its all my imagination but I still believe that there is some reality hidden behind it.
Thank you very much.
