Night Of True Dreams

When Night Of True Dreams enters the
battlefield, create a token that's a copy of target
creature in your graveyard, except it's an
Illusion in addition to its other types and has
"When this becomes a target of a spell or an
ability, sacrifice it".
Illusions you control are Nightmares in addition
to their other types and have hexproof.
"Lock your doors. Trust no voices. Stay awake!"
