Hi, I've found I have an intense psychosomatic reaction to certain bands of blue lighting. I bought a powerful blue lamp on Amazon simply because I liked the color blue, and found it does something interesting to me when I sit in a dark room with this lamp switched on. Not always, because I build a high tolerance to it if I do it too many times back to back, but it's happened often enough.

It feels like a combination of tingling heat, mild adrenaline rush and a feeling of gentle compression on either side of about L1/T12, as if someone has reached right in and is massaging my adrenal glands. I've measured my heart rate in case I simply imagined the sensation. It was in the 90-100 range when my resting is 70-80. Most search results for 'blue light' are negative, but this is pleasant, not like anxiety. It feels almost like an atypical form of ASMR that involves adrenaline instead of sleepiness.

I understand that this could be purely imaginary, but then why is blue light causing me to imagine something so bizarre and so specific? Any ideas? I have some more extensive logs and notes about it if anyone wants them.
