Binaural Beats

I came across something on the web. It is called Binaural Beat

Wikipedia says:

Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves and have been claimed to reduce anxiety and to provide other health benefits such as control over pain.

I tried it. I am not sure if it is snake oil. But I swear... I did get lucid dreams. Usually, I would dream but would forget seconds after waking up. But this time, it seemed so clear, so... real.

Also, at certain points just before I really went to sleep, I could see images...  Interesting.

There are free apps on iOs. You can even mask the tone with music, or sounds of waves, brooks, rain, etc.

Here is the YouTube one I tried before I downloaded it on my iPhone.

Try it. You should wear stereo headphones.
