Small stray signals certainly occur from localizers.  A favorite trick for
instrument rating examiners in Toronto was to use a known bad signal zone
at a local airport (Hamilton) to trap the unwary. The needle would wiggle,
the flag would flip on and off (and sometimes stay on for quite a while).
Obviously, you would not be taken in if you knew where you were (90 deg
off the runway, more or less, and quite far away).  The moral of the story
is that you should always have a crosscheck - in this case, the obvious
one was the NDB collocated with the OM. Quite apart from anything else,
you should be backing up your ILS receiver in case of its failure.
