🌌 Why Sleep Cycles Matter
Your sleep is made of repeating 90-minute cycles. Each cycle includes REM (Rapid Eye Movement) sleep — the phase when dreams are most vivid. If you wake up during REM, you’re more likely to remember your dreams clearly. And if you’re practicing lucid dreaming, timing is everything.
With this calculator, you’re not just guessing — you’re aligning with your body’s rhythms.
