One thing I’ve noticed recently is when I run the Neurophone in Blue mode (theta) and run Dan Winter’s SecretSound tones simultaneously I get an intermittent throbbing at a point in the middle of my skull about halfway back. I kept meaning to document it as it has happened several times now.

skullSometimes it’s so palpable that it feels like someone is tapping their finger on my scalp. I’ve also noticed that I can no longer remember my dreams. Perhaps I’m having the same number of dreams but it is noticeable that whereas before I could recall at least 1 dream every two days I realize I haven’t remembered any since I started using the Neurophone at night. I guess the next test would be to go a few days without using the device at night time.
