Slash's Mind Cave

I was forced to stay awake this morning after waking from an amazing dream (carpet fitters coming today). Which is a tad annoying... I really wanted to dive back into the dream.

I remember being in my old high school. It felt half like a normal day in school, and half like it was some sort of reunion.
My old school friend, Calum, was there. What's cool about that is, he passed away a year and a half ago, so it was seriously good to see him. But in the dream, I was not aware of his passing. It was entirely normal to see him.

I remember it came to home time and I left the school with Calum. We were talking about what to do now. He suggested we go play some Call of Duty. I assumed he meant at his house, then it turned out he meant my house, so I was like "Ohh yeah that's fine, I've got Call of Duty: Infinite Warfare. Ohh and by the way, my flatmate says he's gonna get Call of Duty 1, 2 and 3."
It's weird because the thing about my flatmate was a genuine memory from waking life, but none of my other memories seemed to be active, since I didn't question Calum's existence.

Next thing I remember is being back in school the next day. I remember being in a class with Calum and some other people I knew from school.
The girl to the left of me started touching my hand. So I softly stroked her hand back.
Later on, that girl started touching my arm so I put my hand on her hand. I liked it, but because of being in company, I felt really awkward so I was simultaneously looking around and talking to people.
I was never attracted to this girl while in school, but the way she showed affection in this dream was more than enough to make me like her.

I woke up to find I was curled up in a ball, with my hand on my arm in the exact place the girl was touching my arm.
