Sleep and awake, dream and reality:

Heard death is sleep and birth is awakening from the sleep. Is it really so that the death is sleep? I am puzzled. when we die, probably we connect with Him and reach the place whose existence we always questioned and here we live in a world assuming it to be the reality where everything from relations to possessions have evolved and has a manmade touch.  When I sleep I usually dream. On dreams I have little hold, they develop by themselves as such it could be pleasing or horrifying.  Then what if I am made to live my dream when I am awake, on which I had no command?...
