A married man begins dating a woman via lucid dream technology, but things get strange when she starts appearing when he’s awake.

I like the concept, but I think it needs tightening.

What do you mean by "things get strange"? What happens after the man sees this woman in real life is going to make the difference between a comedy, a drama, a thriller or an adventure. Even though you put this idea in the "adventure" genre, from the way the logline is written at present, it could be almost any thing else. Give us some hint about what happens when "things get strange".

The other question I have is whether or not she recognizes him and was having the same dream? If not, you've got the basis for a stalker film where things could really get strange, but in a bad way. If she does recognize him and was having the same dream, you've got the basis for a romantic comedy.

The logline needs to give the reader some indication of which way the film is headed.

I think this sounds quite interesting - I'd watch it as is. ?Though, I think the actual logline needs to be tightened and refined. ?Maybe start it with: ?Using lucid dream technology....?.

An interesting premise that flips the Freud's concept of "day residue", whereby people, places and events in waking life provide the raw material for the content of dreams.

Maybe something like:

A faithfully married man's torrid affair with a mysterious woman in his dreams becomes real when she appears in his waking life.

I suggest ramping up the dramatic tension by making him a deeply religious person, perhaps a minister, in his waking life.?? But I would ramp up to the state of lucid dreaming.? And I see no need for some pseudo-magical techno fix as with mindful practice, lucid dreams can be induced naturally.

fwiw
