We tracked 3,000+ hours of sleep - here's what over 200 users' nightmare data looks like
Hi all!
We've been researching nightmares and night terrors using wearable sleep tracking data. We've now tracked over 3,000 hours of sleep across 200+ users and wanted to share some patterns we're seeing.
59% of sessions show nightmare-like activity, and 18% involve multiple episodes in a single night. Over 60% of users come back after their first night, which tells us people are finding value in monitoring their sleep.
Curious if this lines up with your experience. Are your nightmares usually clustered together or spread across the night? Do you have nightmares every night? And for those who track their sleep in any way, has having data on your nights changed how you think about or manage your nightmares?
Worth noting that our users are self-selected, so these numbers likely skew higher than the general population.
