Makes sense, I'm actually fond of that generation(and the two prior, it was fun hearing stories of electricity being new, the end of science, etc.). I've experienced similar lucid dreams, where I'm not sure if that was an actual met the family member who had passed or just my subconscious is conjuring up scenarios or messages. Though for some that passed, it didn't seem they were fairing well, if it was them in actuality, but I figured they'd be okay eventually.
I'm open to the possibility too that someone who has passed might be able to communicate through dreams, but found it easier to accept conceptually or not dismiss so readily, if they come just before passing and send a message, than say afterwards.
Whether it's your subconscious or father, I do think the possibility of a visit during a LD great, and find the message you got to be absolutely wonderful!
