Dreaming of Floyd-Warshall

Last night, I was studying the Floyd-Warshall algorithm. I finished at around 11:30, read a little of The Hobbit (I'm rereading it in preparation for the movie), then went to bed.

I dreamed that I was sitting inside a table cell. I was looking up above and watching the empty cells above me get filled in one at a time. The last cell in a row would fill with some gibberish, and then the first cell in the next row would fill. The filling was getting closer and closer to me. Eventually, my cell was filled (I remember feeling very stressed at this point). I looked forward, and watched my neighbors fill. I looked under me, and watched the cells beneath me fill.

Suddenly, I was off on the sidelines, watching another table (that I was not a part of) get filled. Soon after this, the dream ended.

I can only conclude that, in my dream, I was a member of one of the cells in one of the tables of the Floyd-Warshall algorithm. Once the table I was in was filled, the algorithm incremented k and started on a new table.

I notice that I never saw a third table. Perhaps I was in table k == n - 1, and the table in front of me was the last one. Or perhaps this particular version of Floyd-Warshall was optimized (as it should be) to use O(|V^2|) space, and my table (and thus, my life) was deleted from memory after its successor was filled.

Or perhaps I just have really deep-rooted issues, and dreaming about being inside an algorithm is nature's way of warning me that I should see someone.
