Sure you can. Subliminals work in the deep mind, you don’t have to be focused on them to get the benefits. You don’t even hear them consciously, that’s the point. The messages slip in unnoticed by the conscious mind, so there is little resistance.
Then, are visual Subliminals effective?
Subliminal Visual Cues Can Renew a Youthful Sense of Self
The researchers at the Yale School of Public Health found that older individuals who were subliminally exposed to positive visual cues and stereotypes about aging showed improved physical functioning that lasted for several weeks.
Correspondingly, what’s the meaning of subliminal messages? Since the Latin word limen means “threshold”, something subliminal exists just below the threshold of conscious awareness. The classic example of a subliminal message is “Eat popcorn” flashed on a movie screen so quickly that the audience doesn’t even notice it consciously.
