I had a dream, and I woke up crying again! I can't rmb what exactly happened, but like the last time, it had something to do with my Dad =( Indirectly. Like we're talking about him, or something.

Does crying means that I feel stress about something, and does it have to do with the dream or not?

Oh no. I don't know what is my brain trying to tell me =(
To wake up crying, represents some suppressed hurt or previous trauma that is coming up to the surface. You can no longer suppress these emotions. They need to be dealt with head on.

And I also found out that dreaming means that you do not enter deep sleep. I dream all the time. I'm deprive of deep sleep! So scary!
