huh?

I had a bizzare dream this morning.
In this dream, I went back to my primary school to have a 'basic education', but I'm a poly student dressed up as a primary school student. My primary school looks like a cross between the new and the old. I was quite excited and I pound up the stairs as the younger kids look on. I was looking for my primary school teacher, Mrs Toh, but couldn't seem to find her.
At one of the top floors, I look down, and to my suprise, I saw my secondary school teacher leading a class. She looked up at me and beckon me to follow her. I went with her class, and found many young rascals who likes to play tricks on one another. One of them look like Marcus. They tricked the girls who walk infront tp go down the stairs, and they stared at them until the girls realised that they were not supposed to go down. I sort of forgot what other tricks they did, but it was hilarious. We then proceed to the canteen, and then I woke up.

What could this mean?

I've got flu, ulcers, sore throat. I'm probably not feeling well due to the 'heatiness'.
