When you sleep, what do you dream about? ?

One of my recurring dreams is me doing time travel.When i feel stuck in life i use the timetravel "code" to return back in time to a more happy place.Also i sometimes dream i am back in school (and i hated school)>

Usually consists of real life continuation so doesn’t even feel like a dream until I wake up.

Seems like I'm in unknown places in time, but I don't remember the events.

Random things, I don't remember most of it.

That I'm trying to get away from my late Mother and she keeps mocking me, I don't know why as I really loved her

I never remember 

Since being on Weight Watchers, I dream about food.

Sometimes random things influenced by subconscious and things experienced in life, sometimes nada. 

Sometimes cool stuff, sometimes the end of the world.

Most my dreams are fantasy based as if im in a video game slaying monsters lol. If not those, then its people in my life bothering me until i scream in my sleep.
