Last night I dreamed I was flossing a giant's teeth

I'm standing on a scaffolding made of dental floss, and the tooth is the size of a car. Every time I work the floss down, the giant lets out this low, grateful hum that vibrates through my whole chest. There's plaque that looks like moss and I'm scraping it off with an ultrasonic scaler, but it's peaceful, not gross. I woke up feeling oddly accomplished, like I'd actually helped someone sleep better. Maybe my brain is just telling me I've been thinking about work too much, but honestly? I'd take that dream over the usual stress ones.
