Somehow I signed in as a different person

I was adding items to my wish list and decided to look at "My Ebay" wish list for items I had saved.  Only a couple of items were there and while trying to figure out why, I realized I was signed in as another person.  Please help.

Sign out and sign back in as yourself.

Yes, I did that through Ebay.com and also changed my password.  Just curious how a became another user id. Ebay.com.au is okay now for me to sign in. 

It's happened to me before.

A temporary glitch and as dave suggests just sign out then back in.
