Werid but does anyone know what this is?

So I noticed a couple days ago this brown spot on my skin on my toe.

1 person said it looked like I stepped on something

Another person said I’ve got very dry skin & what’s happening is hyperpigmentation. He told me I needed to go drench myself in aveeno skin repair lotion to rehydrate my skin.

& 2 other ppl told me it looks like a bruise.

Idk what it is or how it even got there but it’s kinda concerning to me cause this is has never happened before.

Any suggestions? If it gets any bigger or worse I will go get it looked at but I’ll give it some time to hopefully go away. Excuse my dirty foot. I wear socks 24/7 and haven’t taken a shower yet 😅 no it doesn’t hurt or anything it’s just there…& in the meantime I guess lotion myself down, it wouldn’t hurt anything.
