Where tf are all these mosquitos coming from??

Yesterday, after sleeping the entire day, I went to bed again at night. As soon as I turned off the lights and drifted off, expecting dreams filled with fairies, I was rudely greeted by mosquitos buzzing in my ears. I dislike covering my face with blankets, so I tried to shoo them away, but it was futile. Determined, I grabbed my trusty Thor's hammer and waged war, annihilating over 15 mosquitos! Yet, as soon as I turned off the light, few more threw a dinner party at my feet. I finally had to sleep with the lights on. Despite keeping all windows and doors shut by 4 PM and the bathroom door usually closed, to bhadve kahase aarahe???
