I've had a couple of odd ones recently.
In one, I've bought the missus and I new bikes. The top tubes were chin-high as I stood next to them, and there were extra tubes in the frames that in real life would have rendered them impossible to ride. I seem to realize this in the dream but am polishing them with a waxy rag quite proudly nonetheless. Perhaps this ties in with my penchant for regarding the bicycle as 'utile sculpture'.
In the next dream, my wife and I are trundling a cartload of moulding stock (work tie-in there) down a residential street. We push the cart into the back yard of a home, the occupants of which we don't know. There are two pink cruiser bikes (Treks!) in the yard and we ride them around the cart of mouldings. As I say to my wife "One of these would be perfect for you!", the occupants come out of the house to stare at us. Both are women. One tries mightily to be courteous as we speak with her but it's evident she's somewhat annoyed. The other woman sits on a sofa (in the yard; dreams are so accommodating, aren't they?) and scowls at us with her arms crossed. It's then that I notice that the seated woman is wearing a large strapped-on sexual aid (That's worded as delicately as I know how. Sorry!), and I turn to the other woman and say "Well, I'll bet you'd like us to get this cart out of your yard, huh?".
That one actually woke me up in the night. There's so much going on there that I don't dare examine it very closely.
