If I have a few free minutes, I sleep. I sleep everywhere and whenever, in any position. I sleep in bed, I sleep on the floor, I sleep in the hallway, in the scientific department, on a bench in the park, in a cafe, in the university cafeteria, in someone else's university cafeteria, I sleep in the cinema, at a friend's house, at the theater, I sleep at work, at my parents' workplace, I sleep with a pillow, I sleep without a pillow, I sleep on my stomach, on my back, I sleep dressed, I sleep undressed, I sleep in a jacket, in a hat, in pajamas, I sleep sober, I sleep drunk, I sleep in a plate, I sleep on the keyboard, on the table, under the table... But there's very little time for it.
