Its no delusion. Whenever I drop something small on the floor first thing I do is stop and listen for it to stop rolling around. Then I go and look and it is always right where I knew it would be by sound alone. When someone walks up to me out of sight I know they are coming, how close and how fast, by sound alone.
The XLO setup CD has a great track where Doug Sax walks around a room talking and clapping and when your system is really well set up you can clearly hear his voice and clapping coming from exactly where he says he is, including as he walks around to the sides and even when he goes behind you!
There are a lot of delusions the OP may well be suffering from but hearing the realistic portrayal of a sound stage is probably not one of them.
