What, sonny?

Last night, ThumbSucker talked in his sleep, and it woke me up. Surprisingly, I was engaged.

ThumbSucker: [My name]!
me: Yeah?
ThumbSucker: Thirty-fourth street!
me: What about it?
ThumbSucker: *snore* *snore* *snore*

My guess is he dreamt about the trip to New York we will take in two weeks. But he said he dreamt about marble steps in different colors that lead to the peak of Mount Konocti, the mountain you can see from the house in the LC. Here is a pic. He also mentioned that he was with my mother walking up the steps.

Any thoughts on decrypting this one is appreciated.
