What is dream? My dream?

Been continously dreaming of nightmare after you left.
Normally is a dream that I can't protect you and you died right in front of my eyes.
The torture and the pain in dream always frightened me and wake me up in the midnight.
But recently,  I finally dream something different,  well, not really a big difference but this time I am the one who died and you are the one who live.
Well, I kinda hope this dream is like deja vu and will happen in future, at least I'm the one who is going to hell earlier and you as always go to heaven as soon as you die after living a meaningful life.
Some say it's just a dream but I hope it will happen.
I can imagine when even god is going to abandon me and let satan take me.
In the dream, I'm meant to die, everything that is against law of physics are coming to kill me.
Well, at least this dream is something I wish and hope now.
