Dreams awake

I had a dream that my significant other and I were spending the day together. We ended up in some different situations. I remember him telling me he loved me and my crazy family, and at one point in the dream he came walking up to me carrying a 5 gallon bucket that had green ice cream in it. Also I had spent 24+ hours awake and I also recall walking down a road. Most of the dream was outside and it was a beautiful day

I was awaken about 5am to the sound of a doorbell. This is the third time it has happen in this year

I am being shot in the back of my head. I can feel the sensation of the bullet ripped through my flesh and skull. I know I am going to die but when I awake I can still feel the pain in the exact spot.

I don't know where exactly we were but it looked exactly like my house so I didn't go to school because it would be the last time id see my boyfriend in the dream was my two grandmothers from both side my mother and father. so suddenly something or someone appeared asking if me and my boyfriend were related to anyone near by and when we looked again there were graves inside the house it pointed out at me and I said no. he spotted my boyfriend s grave and awaken him from the dead he saw his son and screamed his name. then he automatically changed into a small girl my boyfriend started to cry and hugged the girl??

What does it mean, when you know you are dreaming and you try to awake yourself?
