Should I Dream or Should i Stay awake??

Dreams
I use to say to be alive you must have a dream
But
I didn't realise dream is just a dream that it all can disappear once u wake up

By the time I am dreaming I heard a Dido's song by saying

"But if my life is for rent and I don't lean to buy
Well I deserve nothing more than I get
Cos nothing I have is truly mine "

I was sitting alone on the grass going to find myself in somewhere, it was windy, cold, silent and leading me no where.I feel deeply sorry that noting I have is truly mine.
I am not sure is that what I found in my dream or is that a song .
After all I lost everything ,I woke up wondering, fearing, doubting .

I am not sure whether I should keep falling asleep or stay awake.

So please !! Let me never wake up if I am dreaming or let me never fall asleep if I am awake!
