Nice to see another Oregonian on the board, Beaverton here.

That was a great movie. A LOT to take in while stoned. I had to watch it 3 times before I could absorb it. I keep getting lost in the artwork.

Anyway, everyone is giving good advice. Not sure if you are a habitual pot smoker or not, but if you are you should probably cut back if you want to focus on your dreaming. Dream journals will really increase your recall even more.

It sounds to me like you were too excited and just gradually woke up after becoming lucid. Just keep trying it and it should improve.
