Today (Tuesday the 13th) is considered an unlucky day in the culture of my birth country, I usually don't pay too much attention to this kind of superstition, but last night I had a recurring nightmare (for the first time in many months), so I had a lousy sleep. Probably because of this, I have had a lot of small problems during the day, careless mistakes, having to repeat things, being in a bad mood, etc.
This may just be a "self-fulfilling prophecy" and the stress of the day is what made me have the nightmare, but it is quite inconvenient, especially since it comes right after a long weekend where work is piling up.
Anyway, as far as "bad luck" days go, this one is relatively mild, so I guess I should not complain, after all, there are many things that could go horribly wrong, but fortunately still go well. I just hope things get back to normal tomorrow.
