Dreams.

The dream wasn't long: it all started with my brother and me deciding to go skydiving. We gathered, boarded a helicopter, and took off. The instructor shouted, "Jump!" Then I don't remember... After we jumped, we were in the air for 3 hours, and we were watching the time. We started to open the parachute, but it got stuck and tore, and we fell onto an island. There was no one around, just us. Then I don't remember. We found a PORTAL. We didn't know where it led. We went through it, and we were back in the helicopter, about to jump. The instructor shouted again, "Jump!", but we refused.
And I woke up.
