If a branch you're trying to delete is not part (or, more correctly,
an ancestor) of your current branch, you'll get a warning that you have
to explicitly bypass by using -D rather than -d.

Still, after deleting the branch, its old tip will very likely show up
in the reflog for HEAD (at the point you last worked on the branch),
even if the branch name won't show up anywhere. After locating the
commit in there it's a simple case of git checkout -b whatever
HEAD@{123} to get back that branch.

One thing to keep in mind is that deleting your branch locally won't
rid you of remote copies of it, so anything that you considered worth
sharing will probably survive even if you accidentally bypassed Git's
warning about deleting branches.

Best,
