For several minutes after I shower, I hear what distinctly sounds like
water dripping in the ceiling over the vanity (not over the shower). I
haven't been able to investigate because the attic is so crammed full
of junk I couldn't begin to get to the affected area.


OK, I got into the attic and cleared a path to the affected area, but
there is no flooring in that part of the attic and the space between
the joists is filled with loose insulation. I can't see any pipes or,
for that matter, the duct from the exhaust fan. The loose insulation
also argues against a drip. If whatever is dripping is surrounded by
insulation, the water would seep into the insulation and not drip.

I'm way to heavy to try dancing around on the exposed joists. Guess
I'll have to call someone.

Not yet. Is any of that insulation wet? Did you bend down and feel it?
Did you swish it out of the way looking for a pipe or wetness, then swish it
back into place? Go up there next time you hear the sound and look for
something then.

I agree with Rick - unless you find wetness, chances are the temperature
change is causing a structural member to make noises until it cools, or a
pipe is rubbing against a structural member under thermal expansion, then
stops when it cools.
