When you say someone's name by accident that you dont mean to say ... Does it really mean that they're thinking or talking about you?

:)  It's happened to me a few times, but I just think it's concidence.

For me, I say my ex's name sometimes, but stop as soon as I realise (before the word is even pronounced).  But that seems to be because I loved her so deeply,  and she ended the relationship not me, so she may never really leave my mind 100%.
Now she wants me back, but it was too late, I'd been nailed down unfortunately.  Oops.
