Dream About Saving A Life In Hospital

I was in a hospital with this girl, we were sharing the same room and we were having some sort of treatment on our bodies, we had hooked up medical equipmemt. I decided to play a mobile game, which was mixed with the hospital. The goal of the game was to sink all the enemy ships and I was this submarine thing that had to sink all of the ships, I failed the first time I played it, so I talked some more with my friend and then I decided to play it again. I was actually winning this time, dodging the other ships bullets left and right, when suddenly I see that there is a ship all the way at the start of the stage in section two, so I torpedo there through the water, and the game starts to turn into the hospital I was in and I'm suddenly running through the hallway to the room I was in with my friend. I open it and see that she flat lined, I start calling over the nurses and I try do CPR. I'm unsure how to do it, because there is various equipment attached to her body, but manage to push it away so I could give her CPR. The thing is, no nurse came, even though I saw them. I thought she was gonna die, when suddenly some of them did come and were doing something off screen. I yell "code blue!" Signaling that a patients heart is not pumping, some nurses take that into account, but when they saw the room they decided not to help me. But a miracle happens, my friend I made, her heart started beating, but I pumped so much it was beating too fast, so I thought I was gonna kill her cuz her heart was beating fast but it actually normalized and she woke up. She didn't understand that I just saved her life but then when I told her, she didn't look extermly greatful, but she looked happy that I did save her. I explain to her that the game detected that her heart wasn't beating and navigated me to her. I wanted to tell everyone I know that I just saved a persons' life, this is definitely my low self esteem talking, wanting external validation, and in that dream I didn't get it, well I didn't get the applause I hoped for, sveryone was just mildly happy I did save her. This is definetly a symbol that I shouldn't care what others think and that their opinion of me doesn't define me
