"Sleep tight" comes from Shakespearean England via thousands of children's bedtimes. William Shakespeare first gave "tightly" the meaning "effectively" or "well" in his 1598 play The Merry Wives of Windsor, where Falstaff asks a servant to deliver "these letters tightly".

By the late eighteenth century the word tight was also used as an adjective and it was in this form that it became part of the rhyming couplet

"Good night. Sleep tight", probably dreamed up by an anonymous mother to wish her young child a pleasant sleep.

Note: tight can also mean "drunken" or "mean with money" but not in connection with sleeping!
