Reality testing
Reality checks through the day.
How to run it
Several times a day, genuinely ask whether you are dreaming and test it — read text twice, look at your hands, check a clock. In dreams text tends to shift and clocks misbehave.
What the evidence says
On its own the effect is small. Its value is in feeding MILD: the habit of questioning your state carries into the dream, where the check fails and the failure is the cue.
Context for that number: only 23% of people have a lucid dream in a given month at all, and 55% have ever had one. So a technique landing anywhere in double digits per night is doing something real — and is still not the switch these methods are usually sold as.
