Dream of brother and cannibalism

This was a really weird one and I haven‘t had a nightmare in a very long time, especially a recurring one like this for the past two weeks.

Every time, I start the dream with immense fear of my younger half brother hunting me down, wanting to kill me. Mostly it‘s bedtime and I‘m somewhere with a friend during a night shift. I fall asleep in my dream and wake up with the feeling of someone standing next to my bed. I always see it‘s my brother with a saw in his hand as if to take off my limbs.

Last night it got especially bad and I ran from him, ultimately ending up in his mom‘s house (we don‘t live together) and my stepsister called the police for me while I tried to hide in the basement. Police came but my brother didn‘t show up. But I had found a bottom flap and one officer and I went down there. It was really cold and dead humans, especially babies and teens were there, as well as frozen meals stating the person whose meat was used.

I literally almost threw up. The officer looked sick as well. He then told me to run as fast as possible, to get out of the country and into hiding before my brother would get to me.

So I took off and ended up in a furniture store where I really wanted to just get ten minutes of sleep but I felt watched. I knew my brother had to be around somewhere and I literally just gave up when a retail worker passed by me and I finally woke up from this hell ride.

I don‘t do drugs and am mentally healthy, so I am very shocked I even managed to make up such scenario.

Now, what does this mean? Somebody pls help me with an interpretation.

Thanks for your help, it is greatly appreciated
