She appears to end up in a beautiful garden with a bed randomly placed in the middle, surrounded by butterflies and flowers.
In the video for "Sail Away" some black butterflies fly away to the sea after singer Lauri is shown walking slowly down a cold-looking beach, singing.
Lauri also sees more odd happenings, such as two children dancing around a wood sculpture (possibly a pyre) in gas masks.
