Needing the loo but all the toilets are visible. Usually it's a really big room, with loads of loos with variants of no door, half a door, a smaller side room that has several cubicles that lock, but no toilets in them, just empty stalls. I have to decide whether to go where I can be seen, or go on the floor in a locked cubicle. If I choose the cubicle the lock fails or I realise at the point of no return that there is a gap around the door and people are looking in.
Being in an emergency situation and not being able to see - either in a smoke filled house trying to get people out before they die, or some other emergency and I just can't open my eyes to see. I'm stumbling around, and I know everyone will die, but I can't open my eyes.
Needing to defend someone else, needing to hit someone, and not being able to. I try to punch but it's like the air is really thick and slows my arm down. I barely touch the person I'm trying to hit. Over and over again.
As a kid I had a couple of recurring ones - a dream of being in a car that wouldn't stop. I'd be in the back and it would start rolling down a hill, I'd climb to the front and the brake would be really hard and I couldn't push the pedal down. I'd have to steer wildly, as the car just got faster and faster.
I also had a really horrid one that was really weird. I was in a big castle, and running from a man that was chasing me. I would run as fast as I could and he would just be walking, but always catching me up. I knew he was going to kill me if he caught me. I'd dive into rooms and lock the door, only to find I'd locked myself in with him. I'd hide in an empty room and he'd come out from under a bed. I'd get into a cupboard and he would turn flat as paper and slide under the door jesus I'm feeling a bit ill remembering it!
