The UK release cut the scene where Alex faces Tommy. It features the infamous nunchuka, which rarely makes it onto the British screen, but it was included in the TV version which was shown on BBC1 albeit minus a few "strong" words.
On the US DVD there is an alternate shot of the scene where the short bald guy with glasses finds his wife cheating on him. Originally, you see the woman partially naked but on the DVD they show only her face.
Dreamscape was the second film to be rated PG-13. The first being Red Dawn (1984).

Dreamscape was apparently only Kate Capshaw's second major role after Windy City (1984)
From her work on Dreamscape, she apparently landed the role on Indiana Jones and the Temple of Doom (1984).
