What, if anything, is the general response to allegation of a "false prophecy" in Genesis 37?

I recently watched the debate between the Apostate Prophet and Jake Brancatella from DebateCon earlier this year. Jake was a touch aggressive and AP was flakey, but a good discussion regardless. Jake pointed out something interesting in his argument that I think demands attention: In Genesis 37, Joseph's second dream depicts the sun, moon, and eleven stars all bowing to him. Israel then interprets this as Joseph being lauded by his mother, father, and brothers. However, Rachel was already dead and thus was unable to bow to her son in Egypt. **What is the generally-accepted solution to this problem?** I can think of four answers, but I'm not confident about any of them: 1. Rachel and Israel already played favorites with Joseph, before the whole debacle. The window for this is pretty small, because Israel was flabbergasted by the idea when Joseph brought it up. 2. This is a post-mortem thing that will happen in the afterlife. This is unverifiable on our end and I think defies logic. 3. This is not about Rachel, but one of Israel's other wives (Leah was also probably dead, so not her. Still, two other potential candidates). This seems like a bit of a stretch, but it's possible. 4. Rachel (and all the other wives) were of one flesh with Israel through marriage, so his actions may turn over to them via association. I don't think there's precedent for such a reading. What thoughts do others have on this matter? I'll be the first to say that I may be missing a simple answer somewhere.
