I have this script I'm working on wherein the main character has numerous dreams. I know normally you'd start off the scene with "Begin Dream Sequence" but in several points in the script I want the audience (really the reader at this point) to not know it's a dream until the end of the dream. So if I leave out the "Begin Dream Sequence" but later in the scene (or the beginning of the next scene, i.e. "She sits bolt upright in her bed with a gasp") is that "allowed"? Can I get away with that and not have the script format gods descend on me like a ton of bricks? I can see where in later versions it's important to know but for that oh so important first read I don't want to tip my hand.
