Shambolic

I had a dream last night where a colleague of mine was telling another colleague how his credit card had been mistakenly charged. Somewhere in his remarks he mentioned a word which I didn't know the meaning but could only guess. The word sounded to me like schamboly. Mind you, in my dream I heard, not read, the word, so I just made up the spelling.
When I woke up I looked up the word and the closest I could get was shambolic, which was what I guessed what it meant in the dream. I'm not sure how I could have guess it correctly. I try to rationalise that by thinking that perhaps I have heard and understood that word before then forgot it but somehow it has sunk in my subconscious memory. Maybe, maybe not. As of now I have hardly any recollection of my first real encounter with that word.
Isn't it strange what dreams can do? A friend of mine told me about his dream. He dozed off in his sofa. In his dream the phone was ringing and when he picked up the phone it was his sister in another country half around the globe. He woke up, the phone was ringing and when he picked up the phone it was his sister in another country half around the globe. Sorry about the sentence repeat, but for a moment it was life imitating dream. Now, he told me that the sister usually called him once a year or something. Was it merely a coincidence that he guessed it right in his dream?
By the way, shambolic means chaotic or disorganised according to http://en.wiktionary.org/wiki/shambolic. The root is shambles and apparently is a British slang. In my dream, that colleague of mine was American and he didn't look like any of my colleagues I know. Weird.
