This dream happened around 5th grade.
I was floating above a empty grassy field. It was flat. I raised my hand up and dotted liners appeared in squares. I thought of something I wanted. A blue castle with rainbows and unicorns. Dragons flew around it. I smiled warmly at seeing this. I made a mansion with a giant T on it. That was my family's dream house. I summoned more and more things mostly sticking to the fantasy theme.
Then I woke up.
I had this dream once.
