Unless it’s a big waste of time and money.
The only limitation is your imagination, and without any of the bad things involved there’s not a lot of reason not to try it. If you’re feeling stressed they can help you relax, if you can’t get to sleep you can take an audio Ambien. But are we there yet? The makers of I-Doser say that we are, and that if you follow their steps to a good listening experience you can start to fee a myriad of moods and effects based on what your goal is. It seems like sometime in the future humans will be able to virtually simulate all sorts of experiences, including ones that alter the state of mind. It definitely has a sci-fi feeling to it, but is the science there to back it up?
The concept behind I-Doser is pretty mind-bending when you think about it, being able to elicit experiences just by listening to an audio track.
