Is this real? I’m about to go try this, but I’m scared its something like a weegie board with music.
In more simple terms than the above link: Making one ear have a different frequency (pitch) to a sound play for a while can cause you to became relaxed or focused, depending on how different it is. It can also supposedly cause Sleep Paralysis if you try to fall asleep while its playing, which is why I’m scared of trying it. Any suggestions?
