Dream About Sister Baby Death

I had a really weird dream it started off with my sister Sophie and then after we went home (she’s pregnant) and we had a argument I called her 2 faced and pushed her then it fast forwarded to Christmas and my sisters baby Oliver was born so I went to go pick him up and I forgot to support him by his neck and it snapped (he died) and then I dropped him from shock and killed my self infront of my sister it then went blank and then I woke up in a hotel went to the toilet and looked in the mirror and realised I looked ghostly looking then went to try and go out but I couldn’t I was trapped then I woke up out the dream
