A girl I think named "feana " in her life all strange happens and she solves it out and ultimately each episode ends that strange happens to be for aliens or ghosts like that a TV serial mix off aliens and ghosts misteres around in 2000 TV program

Sounds like it might be this:
So Weird (TV Series 1999–2001) - IMDb (http://www.imdb.com/title/tt0169247/)
(main character's name is 'Fiona'... )
