Question

What is subliminal messages?

Answer 1

Subliminal messages are messages that only your subconscious mind notices (you don't think you notice them, but you do)
For example:
Say you watch a coke commercial, and it has music, Say the song is something classical with no lyrics.
So, you're watching the commercial, and the producer f the commerical has added "Buy Coke" in the background of the music very quietly and you cant hear it. You're subconcious mind will notice it and you may feel the urge to buy a coke after watching it and listining to the message.
you could also search "subliminal messages in advertsinig" on youtube, there are loads of videos where they point out the messages in commercials.
