Table 1. Sleep patterns and dream recall.

Low: Low screen time; High: High screen time group; P value<0.01 for Efficiency, Dream Recall Frequency, Night Wakings (per week), and Daytime Sleepiness (%), are derived from independent samples t-tests for Sleep Efficiency, Night Wakings, and Daytime Sleepiness, while a chi-square test or Fisher's exact test have been used for Dream Recall Frequency, all indicating statistically significant differences (p < 0.01) between the two groups.

Variables	Low Screen Time Level (N, 500)	High  Screen Time Level (N, 500)
Sleep Efficiency (Mean ± SD)	90% ± 5%	75% ± 5%
Dream Recall Frequency (Mean ± SD)	70% (at least once a week) ± 15%	30% (regular dream recall) ± 10%
Night Wakings (per week) (Mean ± SD)	0.5 ± 0.2	1.5 ± 0.5
Daytime Sleepiness (%) (Mean ± SD)	20% ± 10%	60% ± 20%
P-Value (Mean ± SD)	<0.01	<0.01
