Games and physics simulations need to detect which objects are touching or overlapping. With nnn objects, checking every pair is O(n2)O(n^2)O(n2) comparisons, which gets expensive fast. A hundred objects means roughly 5,000 pair checks. A thousand means nearly 500,000.

Setting up your actual Sleep Routine takes a little more time and intention. A Dreamie Sleep Routine consists of multiple steps, which you can use all, some or none of for your custom routine. Those include the Bedtime Cue, which lets you know it's the time to start getting ready for bed (you designate this time); the Wind Down, or the sounds you'll fall asleep to; and the Noise Mask, the sounds that keep you asleep. If you wake up in the middle of the night, there's a Back To Sleep option too.
