It is lame. But its the only way to be sure. And, thanks too Prometheus (and I think the ADF novels too), these vivid dreams are canon.
Look it sucks - we all agree it sucks. It's a sucky way of fixing the "problem" if you want a seamless Alien 5.
Ignoring it... IDK... maybe. I'd be happier with an allusion to dreams ... I don't even think we need to SEE the Fury 161 dream... just know that she has had it.
But I've really given up on A5 (as envisaged by NB and others - I suspect by the time they got to it, wouldn't Sigourney Weaver be too old to do it? I mean, she was amazing in Daredevil, but this imaginary movie would be like five years down the road, wouldn't it).
