I wouldn't necessarily say they were related, no. This happens all the time in my house with a variety of doors; if the front or back door is open, or a window or two is cracked open, even very slight gusts of wind, almost un-noticable ones, can still give enough momentum to slam doors rather suddenly and loudly. That would make it seem likely that it was just a purely naturalistic event; to say that it might be because of astral projection practices seems to commit the logical fallacy of "Post Hoc Ergo Propter Hoc", meaning that, you do something, and then something happens at a later point, and you say that the one caused the other, which could be true, if there was evidence in place to support it. ;-)
I'd say it was just natural air and wind currents and variants, but hey, that's just me. We'll see what others have to say.
And, since this is in the "Introduce Yourself" forum, I'll gather you're new here, in which case, welcome to the site. :-)
