a concept

I used to. i used to have dreams; many different happy dreams; and the lights were on.the joy were there and the pains were gone .the sky was dark blue and so shiny was the sun .....birds....butterflies....roses...were there ...i was having fun all the time..i used to have dreams.
But i used to have them disappeared.
i woke up ..look around every thing gone...............
The door is lock..the light is off..no shines...the sky is dark ...the bird fly away ..and no place for fun .
it's really unfair.......to have all your life....as a nightmare !!!!!
But i used to.
