Why do we have the ability to have such terrible dreams?

Question

My dream last night was a long one, and in two parts, and most of it was nothing but fun, memories, and things I wish could happen.

Except one thing.

My brother was killed in my dream.

Throughout the rest of my dream, I tried to act fine, but any time someone would look away I started crying and bawling. There was such a realness to it, and I felt the heavy pain in my heart throughout the dream, especially because in it, my own sister didn't know.

When I woke up, I was so d**n thankful to hear my brother opening his door and just using the bathroom; he's ALIVE! But I can't stop feeling so sad. The heaviness is still there, and I know that if he did die, it'd be worse.

Why do our minds have the ability to think such awful, terrible, or the worst thoughts when we're asleep?

It's not fair.

Answer 1

dont be sad death signifies  news of a birth if you are not the one that died ...speaking to a dead person also is good news to come...lets hope that the dream made you so emotional that its a good thing coming your way...

Answer 2

The reason why our mind is capable of making such aweful dreams is because it helps increase our chance of survival. The ability to have bad dreams serve as allegorical warnings from the subconscious about some evidence of waking situation that may be problematic or dangerous that the awakened conscious has ignored or supressed.

Answer 3

I've died several times in my dreams, in very unpleasant and painful ways. Our darkest fears are often the ones that we wish to turn away instead of confronting and defeating. When we dream, our subconscious brings these fears up.

Edit: h**l if I know. Lots of my questions get funneled to "mental health" for some reason @_@.
