I Dream of Onions

I woke up this morning and remembered dreaming. They say that we each dream every night, but only remember dreaming occasionally. If we don't remember dreaming, what good is it? Anyway, this time I do remember. In my dream, I was walking along what is known as a "dual carriageway," here in Britain. In America, we'd call it a "divided highway." The point is, there's a "central reservation" (UK), or "median strip." (US) In the dream, I am walking in this center part, on the grass. All of the sudden, as I am walking along, looking down...
There's a tendency to look down, when your life is crap. It's as if you keep your head down, then no harm will come to you. Kind of/sort of a "see no evil" strategy. Or, the mindset of an ostrich. If you don't see it, it can't see you. It's not so much being scared, as it is feeling tired. Don't make eye contact with anyone and maybe they won't try to speak to you. Anyone who speaks to you must want something. Sometimes you can feel tired of being confronted with everyone else's wants.
Another reason to look down when you're walking is that you might find money. That does happen, sometimes. Still, I think the main reason is tiredness. Being tired of the constant grind life seems to have you under. "Leave me alone. I just want to get home and have a rest."
All of a sudden, as I am walking along, looking down... I see onions. A whole field of them. The grass seems to be full of them, still growing. I start picking them up, as many as I can carry. I am thrilled to be getting these free onions and carry my bounty home. What's it all mean?
