Is it normal that i get dreams of murdering someone and feeling guilty

Is it normal? I got a dream tonight where I murder a group of people, pretty much without a reason ( I was standing behind them and I think I didn't really have any reason to not want to be seen) and I just decided to murder all of them (8-9 people)
Afterwards, I was home and I felt extremely guilty (ofc) and I felt shame and self-hate . I screamed and cried it out loud to my mom and begged her to call the police. She stayed calm but couldn't say it so later I called the police but the words didn't come out of my mouth. Same thing happened a second time I called, but then I woke up. I got many dreams similar to this earlier(not really lately it often but it has happened). Every time it's different, but the pattern is that: I kill someone very casually and without a reason, I get extreme guilt, and then I wake up in the middle of that and get scared. And every time , in the dream I just think to myself about all the earlier dreams I had about this and think "I hope this is all a dream" but then "oh God, it's not a dream this time!"
