Had a dream that my dad got murdered, but everyone hid the cause of death from me.

I had a dream that my dad got murdered. At first I didn’t know the cause of his death because everyone hid it from me, later in the dream I found out that he was beaten to death with a chopped-off foot.

I read about his cause of death from my girlfriend’s phone, got frustrated and went to check with my mom who told me about the details. I got extremely sad when I heard it and woke up after.
