Well it won't be forced, but you can practice lucid dreaming. When I used to do it, I kept a dream journal (in which you write every detail of the dream that you recall immediately after waking up) to improve dream recall+awareness, and in real life I continually looked for events or things that confirmed I wasn't dreaming (hands, mirrors, clocks, gravity…). Once that's habitual it should transfer into your dreams and you'll become lucid once you notice some kind of discrepancy between the dream and reality. From there you can practice exercising control over the dream. Spinning around supposedly helps keep you in a dream state if you feel it fading, but it never really seemed to help me idk
In my experience I've noticed improved dream awareness after falling asleep again immediately after waking up. Sleep paralysis becomes super frequent once you have high dream awareness or waking half-up after a lucid dream ends; but even though the paralysis can be scary, if you learn to relax while that silhouette is standing there over your paralyzed body while you frantically try to move, you can transition straight into a lucid dream.
tl;dr not hypno but keeping a dream journal will improve your dream awareness and should also increase the apparent vividness of the dream
