Think one of four short dreams just may have been some kind of teaching dream.
I'm sitting in the aisle seat of an airplane and someone ( teacher) is standing infront of everybody facing us and tells us all to look ahead.
The cockpit door is open and we can see the clouds through the cockpit window from where we are. As the instruction is to look others get up in the aisle to look but I stay seated. I had thought we were coming into land and they should have kept their seatbelt on but the teacher just encouraged them to look ahead.
We weren't landing and the sight was amazing to see the nose of the aircraft cut through the white puffy clouds outside. I still felt the amazement as I woke.

This may be my problem currently of focusing in the brow. I'm not still enough and keep changing my mind after a few minutes to start trying to visualise something.
I wonder if this was related to the scene where someone was axing through a blackboard making geometric patterns at the same time. He was cutting through to the other side of a blackboard?.
