Its funny you say that one twchnique for lucid dreaming is focusing on mundane things that you do in everyday life and within a dream the behavior is different. A friend actually used light switches as anchors so whenever there was one in a dream he would realize he was dreaming. Im not a practitioner so im not 100% sure how this works in practice but I remember him talking about light switches specifically

A great way to become conscious in your dreams is to notice something that isn't supposed to happen while you're awake. For reasons I'm not sure why, many people share a lot of experiences that happen in dreams that work well as anchors; your hair falls out, you look in a mirror and have missing teeth, technology doesn't work the way it's expected to, light switches don't work, clocks don't display a proper time or you can't read them, and more.

There are more ways to purposefully check if you're dreaming, such as by trying to push your finger through your hand, or breathing through your nose while you pinch it with your fingers. But some of the examples above just passively happen while you're dreaming and you can train yourself to notice them.
