Repeat the Nightmare

When I was young, there was a nightmare I would have again and again but it was always the exact same thing.
This went on for a solid 5 years...

With a pin in one hand and a paint tray in the other, I'm alone in my family's home. Everything is gone. The rooms are empty. I stand their and stare at the wall.
Without instruction, I know that I have to paint all the interior walls with what is in my hands.
Colouring in the surfaces using only the Pin point.

With a sudden breath, I'd Wake up with sweat covering me and my heart thumping.

Why was I so afraid of this dream??
This dream never lasted long. It was only this scene. Each dream I was standing in different room but I never moved from that one spot.

I was around 12yo when I had this dream for the last time. It came to me early in the night. I woke up with a start, and lay there frustrated.
I fell back asleep eventually but only found my self back in the same dream. But this time I could move. I walked up to the wall in front of me and began; dipping the pin into the paint and covering cm by cm of the wall.
I did every wall of every room and wall way of my house.
Mentally etching every stroke onto the walls.

This felt like hours upon hours. Dipping and scribbling. Dip. Scribble. Dip. Scribble.

The moment I finished the wall, I came out of the dream.
Lying in bed, It was just another day. Yet mentally 3 days had passed.

I never had this dream again. But I am still confused as to why such a huge task got to me so much.

The Never ending story

I had this dream once where i kept replaying the same situation but i was a different character each time seeing the the scene from a differnet angle.

Longest dream od my life.
