help me understand the meaning of this symbolic nightmare

Last night around 3–4 AM i had a dream that i honestly still can’t make sense of.

I was in my own room. It was nighttime and the environment was quite dark. We were sitting across from each other on the floor; next to me was a male friend with whom i am actively in contact in real life.

The atmosphere was calm but strangely intense. When i looked at my hand i saw 3 4 black letters near my pinky finger. I said that I wanted to erase them. The friend next to me insisted that i absolutely shouldnt erase them and said that these letters were from the protective surahs of the religion i believe in.

As I looked carefully at my hand, the letters appeared dark and clearly visible. I thought about erasing them. At that moment my friends eyes turned completely black and the room became even darker. A black, smoky aura formed around him. Interestingly despite all this darkness i wasn’t afraid. I just watched what was happening as if something was trying to be conveyed.

Over the past year i’ve had quite difficult and exhausting experiences. Their effects were still making me sad. A few days ago i decided that my sadness had gone on for too long and wasnt worth it anymore and i made some decisions to leave everything behind and reorganize my life completely.

Seeing this dream right after making those decisions caught my attention. Im wondering whether its connected to the decisions i made or if it carries a completely different message. I would be grateful for any interpretations.
