Experience, experiences

[Unregistered]

Hi teacher,
is possible to use word experiences? In what case?
I have seen it written so many times that now I don't know whether it's correct or not.

Thank you.

It's a count noun, yes; An event or a series of events participated in or lived through.

...she gave an account of her experiences with Ratcliffe.

Three seniors share their experiences of falling.

There's a difference in meaning here,

The staff talked about their experience (i.e., their expertise).

The staff talked about their experiences (i.e., their expertise).

The staff talked about their experiences(i.e., An event or a series of events participated in or lived through).
