How could a lightbulb start working again after not working for months?

In my room I have some fairy lights hung up on my wall. One bulb blew quite a few months ago and I kept meaning to replace it but never got round to it. Yesterday I turned on my fairy lights and the bulb that was out is working perfectly fine. How is this possible? I know it's a strange question, but I'm just curious.

    Likely answer: there was a loose connection that has been knocked back into place and now the bulb works again.

    Unlikely: someone broke into your room just to replace a fairy light bulb.
