it can look like he fell off the stage but not really he's just falling to the edge, idk how we would do that , but illusion

wailing noises on speakers, some loud, some low

we can do something with the over head lights for this

pot bubbles over with foam

this is where the snapchat or instagram thing can come into play with the phones being held and the ghost is shown through that medium

throughout the play they can have shadows following them to depict how they feel, their demons. it can be done with a projector or a screen behind them and people dressed up behind them as demons so it looks really cool and they follow the actors movements or go about it separately to depict the underlying meanings if that makes sense

if he had a cape he could whip the cape behind him, or when he exits a flash of fog and he's gone, kind of like a magician because this play has alot of magical elements too it

when Macbeth enters make it super showy, lights brighten and then dim back regular. but light is like red and bright centered on him, but then scene proceeds like normal

she can have a dead swine's ghost following her (projection) or fog

sergeant can have blood and guts pouring out, but it could be like a slight of hand trick where it looks like that to the audience because of the lights and a projection, but really he's laying on the stage with nothing because it's hard to clean up that stuff.

at this point we could do. something where it looked like lightning struck a tree, or have an image of a tree splitting behind them and a loud cracking sound like thunder
