brain, triying to control the soul inside the physical body. Not easy wander between this world and that world. Making us believe we dream when the truth is we travel. No dreams just trips to other times.other dimensions. Brain tries to make us forget those dreams and most times he does it. Thats why we get this urge to move on. Travel .see places. Its there, weve done it. Falling in monotony,frutrates soul, and brain can no longer control it, and we get bored, tired.
