Why can't some people sleep if they are in a strange place?

cause theyre not used to sleeping in a strange place

     Being comfortable with yourself,
knowing yourself, being one
with the universe in this knowledge,
then...wherever you lay your head you are
at peace.
...unless of course that jackhammer being
used in a construction project just
won't let you sleep...Or maybe the bedbugs
are biting you and keeping you awake.
or...??...haha
