One Type of Dream Could Make Your Sleep Feel More Restful, Study Finds

Researchers from IMT School for Advanced Studies Lucca studied sleep in 44 healthy adults.

They collected data across 196 nights in a sleep lab.

Participants were awakened during dreamless sleep phases and asked about their dreams and how rested they felt.

The deepest sleep ratings followed both deep unconscious experiences and vivid, immersive dream experiences.

The shallowest ratings came after fragmented experiences, and the analysis focused on N2 sleep and delta/gamma waves.
