The shell glob .* expands to everything in the current directory that
begins with a dot.  Which includes "." and "..".

"." is the current directory.  ".." is the parent directory.  E.g. when
you type "cd .." it moves you "up" to the parent directory.

Asking ls to show you .* is usually a bad idea, precisely because it
expands to a list which includes . and .. and does exactly what you
just described.

This is why the ls command has -a and -A options.
