The Sixth Sense (1999)

In M. Night Shyamalan's haunting, twist-ending signature film:

• the startling opening sequence in which Dr. Malcolm Crowe (Bruce Willis) was shot (and killed) by angry ex-patient Vincent Grey (Donnie Wahlberg)
• the anniversary date dinner scene of Crowe with his troubled and depressed wife Anna (Olivia Williams) in a fancy restaurant
• the scary scene of frightened, paranormal and tormented 8 year-old Cole Sear (Haley Joel Osment) hiding in his tent, shining a flashlight under his chin and seeing pale ghostly young girl Kyra (Mischa Barton) with bloodshot eyes vomiting up her morning oatmeal next to him

Cole's Sightings of Two Ghosts

• the scene of Cole telling his divorced mother Lynn (Toni Collette) a comforting message from her dead mother - as a bloody car accident victim appeared in the car window behind
• the final 'reveal' scene of Dr. Crowe's wedding ring (not on his finger) rolling noisily in a circle across a parquet-wood floor - with the startling revelation that Crowe was one of the "dead people" seen by Cole

Dr. Crowe's Realization That He Was Dead

• the famous line of dialogue: "I see people" followed by its real meaning: "...They don't know they're dead. They only see what they want to see"
