"Dream, dream dream...." joke

After she woke up, a woman told her husband, "I just dreamed
that you gave me a pearl necklace for Valentine's day. What
do you think it means?"
"You'll know tonight." he said.
That evening, the man came home with a package and gave it
to his wife. Delighted, she opened it-to find a book
entitled, "The meaning of dreams."
