What is this on my glass?

Hi:

This just appeared on my front glass over night. I need help identifying ...

Thanks!

Could we get images under white light (ex. With a flashlight)? It’s hard to tell under blue lighting, but the object might be snail eggs, snail mucus and sand, a worm, or maybe something else.

I will take another picture under white light tonight.
