if you swish a carbonated drink around in your mouth while plugging your ears it sounds like rain falling. i used to close my eyes and do that to help myself calm down when i was Young and Extremely Anxious. it sounds like a rainstorm in the middle of your head.
About headaches - if you don't want to use medication, you can try a number of things. Ear plugs can help remove some of the stimulus, as can sunglasses. Try using an ice pack (I like the ones from Dollar Tree that are ice masks and $1, I bought five and just leave them in the freezer). Often I'll put it at the base of my skull (another reason to like the eye masks, they come with straps to hold it in place). Switch between base of skull and temples/forehead or crest of head.

Help for the headache anon:
continued: palpablenotion said to askaboutautism:– can help calm a headache/migraine, if you aren’t too smell sensitive (I usually am though). Sipping at your favorite caffeinated pop can help (coffee should probably be avoided, tea can be beneficial I hear but I can’t stomach brewed beverages so I’m not sure). Sometimes “grazing” helps me - I keep a jar of oyster crackers or mini saltines with me at all times. Depending on your headache, sometimes salt can actually help. You can also try physical stimulation. Rub gently at the temples in small quarter sized movements. Carefully pinch the daith in your ear (the very short, central fold parallel to the ground, google it but be aware that many images show piercings as a daith piercing is the new trend in migraine prevention/treatment). It’s a pressure point and can help. Place your fingers where your hairline and neck meet so your finger tips are almost touching and palpitate that muscle. Same with the muscles between that point and the ears.
