>I get a little creeped out

Maybe you already know, but this 'it's all just a train of mechanical compulsions, there's nobody in here' is the very thing that meditation is intended to allow you to realize, it's the 'liberating insight'. The problem with just reaching it on your own is you don't get the other part, the viewpoint about the world that build the case that this is a good thing, a great thing (believing there is someone there is the cause of all the dissatisfaction you ever feel). So you could check into that if you want - ajahn brahm or suchlike
