There are smart bulbs with dimmer and timer functions you can set for the same sunrise effect.

My husband doesn't even have an internal voice! Thought he was joking but it's A Thing. He gets the words translated straight into images, like in a play when a spotlight illuminates character or scenery as it's described.
