The famous surrealist artist Salvador Dalí had a strange habit. When he could not solve a problem or had difficulty coming up with an idea, he chose to nap. However, he did not nap “normally” to say - he used a unique method.
First, find a comfortable sofa or armchair, a spoon and a large plate or pan. Sit in a comfortable way, flip the plate over and place it on the ground, then hold the spoon directly above it with only your thumb and index finger. While thinking about the problem you want to solve, fall asleep.
As soon as you enter REM sleep, all of your muscles will relax and so the spoon will fall onto the plate, making a loud clatter. As soon as you get woken up by this, you will not only feel well rested, but also discover the solution or idea you were looking for.
