I think that Ran's bad dream is that Keiko might get an husband and a kids on her own and leave her ......
It's not just Ran's, I think everyone here fears the same thing.
Let's hope this doesn't go the typical "I love you but I want kids, brb gonna find me some dick, see ya" - way.
No, not everyone. I said, further up the page and another member said on a previous page, that maybe Ran is just really worried about Keiko because she saw and was with Keiko during those moments when Keiko was having nightmares. You can think you're over an issue but sometimes a little hare trigger could easily throw you over the edge before you realized what happened and, recovering will be just as difficult. So seeing Keiko with a kid like that all of a sudden, you bet Ran would be really worried, especially after seeing and helping her through those nightmare moments. If anything, Ran suggested boozing to help herself and not celebrate the fact that Keiko may have coped and overcome her nightmares.
Seriously, I don't know why everyone is jumping to the conclusion that, no more nightmare = bring on the penis!! Keiko seems pretty content with her life right now and the last relationship seems like it may have been her wake up call.
