"Dreaming that your loved ones were killed is very miserable" is related to your long-term watching movies or games. My friend, you just had a horrible and weird dream, which has no causal relationship with real life and does not need to be connected with reality. It's just a strange dream for you to establish such an understanding in your mind. When I wake up, my dream is gone, and I will enter a new day. Don't deliberately interpret dreams, causing you unnecessary worries and entanglements.
Forget this dream and have a happy day! ?
