When college professor "Matthews" (Nicolas Cage) starts appearing in the dreams of strangers (oh, and his wife!), his whole life is turned topsy-turvy. Initially it's all a rather benign phenomenon with his appearances fleeting, inconclusive and harmless. Until, that is, he meets one person who has been having a rather more intimate experience. Not only does this meeting not go very well (on various levels!) but it seems to change the very nature of the illusions for everyone, turning them more into nightmares... A predictable, occasionally violent, backlash ensues which makes the man's life - and that of his family - all but insufferable. What to do now his fame has come back to bite him? I quite enjoyed the first half hour of this quirky and entertainingly written drama. Cage is always rather good at taking the rise out of himself, and he seems to be enjoying the ride at the start. Once the story turns a bit darker, though, it runs out of steam. It's charm and uniqueness becomes rather subsumed in a rather unsubtle whack at the "cancel culture" that exists amongst those who live their lives via social media. It's not the first or the best to draw a parallel between what's real and what's fact - even when such distinctions are easily identifiable, and after a while I felt the film had no clear idea of how to conclude without actually proving it's own, rather depressing, point. The idea is interesting, the delivery is fine - but the end product is all a bit underwhelming.
