Glitch in the matrix?

Something weird happened the other day I had this thought crossed my mind that I needed a blue shirt I don't know why that thought came in my mind but when I turn around there was a blue shirt there that was not there before that did not belong to me I grabbed it looked at it through it with the other clothes and it seem to disappear as quickly as it reappeared when I went to show somebody the shirt later that day wtf is this weirdness
