EEG microstates of dreams

In short

The authors compared brain activity patterns just before people woke up with or without remembering their dreams. They found that specific, brief brain states were more common during awakenings where dream recall occurred than when no memory was formed. This suggests that the timing of these distinct neural patterns determines whether a conscious dream experience happens while we remain asleep.
