Thanks for the reply. ♫
It would certainly be great to be able to practice situations like this in dreams - of course I could practice right away in waking life as well, but I feel that it would be a heck of a lot easier to start in a "private" environment like a lucid dream; that way I could get comfortable with the approach attempts without risking to make a fool of myself in the beginning (although of course I wouldn't necessarily actually seem foolish unless I do something really stupid, but still).
