Senses Initiated Lucid Dream.
How to run it
After a WBTB waking, cycle attention through sight, hearing and touch — a few seconds each, several rounds — then let yourself fall asleep.
This one depends on waking at the right point in the night, and “about five hours” is not precise enough to act on. Work out your own alarm times from your bedtime — the calculator uses the 90-minute cycle so you wake between cycles rather than out of REM.
What the evidence says
Popular on forums and untested in the literature. Included here because people ask about it, and labelled accordingly.
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.
