Large and random Lighting payments concern/question

I have a lightning wallet for spending and sending small amounts. I haven't used it in quite some time but today I have received multiple payments of a few sats a few $4 amounts, and even a $9 payment, in 24 hours.

Is this something to be concerned with? Why am I receiving so many sats out of no where?

I am going to just hold it for awhile before moving it but what is this all about?
