Deja vu?

Have you ever had those unusual incidents....Like when you hear something for the very first time and get the feeling that you've never seen or heard it before..And then you start seeing that same thing everywhere...On posters, television, in magazines,etc and then you hear people talking about it...Something that you've probably never cared to notice before suddenly comes forth everyday..It's a strange feeling if you ask me.. Something that's been in front of you for so many days, which you've suddenly come across keeps appearing again and again...deja vu anyone?
