A few more notes on dreams

I remember when I used to have
"shower dreams,"
when I was so tired
that my head, still half-asleep,
functioned in a dream-like state
in the shower,
sometimes trying on
in vain to continue the dreams from just
minutes before.
I usually only "dream" when
I sleep in, and not when I stay up late
and sleep in even later, but
when I get to bed at a decent hour
and sleep in a couple more hours than normal,
that's the magic hour—
that's when I dream.
I've heard stories that
certain foods cause you dream,
but I've been too scared to purposely
try them before bed,
something about manipulating my mind scares
me, let it manipulate itself for all I care,
I'd rather there be some magic to it,
let dreams be dreams.
