I’ve never dreamed (to the best of my knowledge, but I doubt it, I’m 50 years old and I think by now I’d have some inkling if I dreamed at night). Do you have any data on longevity of non-dreamers?

Everyone dreams, you just don't remember your dreams. Though we're interested in REM, it isn't our focus atm...and yes, you dream in non-REM sleep, but those sorts of dreams are different.

REM (dream sleep) is thought to be connected to resolving emotional stresses. I haven't seen any research on the reduction of REM sleep and the impact. Sorry.

Is there actual proof that everyone dreams?

My understanding is that neurologists are taking this from EEG readings and that even people who say they "don't dream" show the same telltale markers of dream as people who do dream.

how would this work if you have a partner?

We're only measuring your brain waves, not your partners :) we play sound through bone-conduction, so nothing in your ears, nothing covering your ears, only you can hear it (there is some sound leakage, but minimal).

Completely forgot about bone conduction (I was thinking bed side speakers disturbing your partner, or conventional headphones disturbing you), but still you need it strapped on - a slight discomfort. Also, since you mention measuring, there is another component strapped on (unless it is a fabric woven sensor). An image search on EEG produces cumbersome looking devices.

yeah, we've got soft fabric sensors and the bone conduction speakers are amazingly small. We're still working on comfort with our prototypes - but we're getting pretty good.

Our industrial design firm has nocked it out of the park with design, and we think there stuff will have a huge impact on comfort. Still needs to be tried.

Sounds really interesting, best of luck!

You mentioned trials, are you trying to get FDA approved?

We're just looking at FDA atm. We don't have to get approval, but we're looking at registering as a medical device (Class 1, maybe Class 2).

Do you have any experience with that process?

We're implementing existing research, with a bit of our own spin on it. My co-founder and I both come from CSIRO (Australia's Science and Technology Org), so our trial is a combination of measuring that we've implemented the science correctly, it's having the impact we want/expect, and we can prove it.

This isn't a medical trial, but we are following regular research protocols.
