This morning, I recalled 7 dreams from the night before; one of them, lucid. Two days prior to this night, my recall was below average.

I thought of differences in my daily routine, and the only moderately odd activity I took part in was taking a long swim in the neighborhood's community pool.

Does swimming (lowering the core body temperature mildly) actually increase dream recall? Or is remembering one's dreams an unpredictably erratic process? (what I've been experiencing.)
