A Wake Up Script I Made From Scratch

[Streetboat]

You should play around with FadePlayerRollTo, and make it so you start off at a 90 degree slant, insinuating that the player is lying down, then have it roll up to normal position.

Another thing to take note of, is if the player is indeed awoken with a gasp to a loud noise, wouldn't it fade right in as you bolt awake? Something neat you could do is set the SepiaTone and Radialblur to a high degree while the screen is faded to black (so, right from the start), and then when the player bolts awake, have those gradually shift back to normal to simulate grogginess.
