We're not sure what these are, the closest thing we could come up with was "zits." A few weeks ago, we noticed these weird drips sliding down our bathroom walls that looked a lot like dried wood glue, maybe a shade or 3 darker. It came out easily with disinfectant wipes, but we tried to find the source of the issue. Then, during a shower, we looked up and EEEUUUCHHHH!!! These brownish bubbles were slowly forming on our white ceiling! Granted, when we moved in, the bathroom was the only room we didn't have repainted. But now we're wondering if this is 1) dangerous and 2) easily fixable?And anyone have any ideas on what these gunk is? Help!
