Β A cat has lived in the house for some time. A ghost cat rotates around me from time to time: I'm pursued by the feeling that somebody foul touches my legs. In fact, somewhere in the subconscious mind, the brain is afraid to approach a new member of the family and sends me signals to keep me alert all the time. It’s very similar to phantom signals from a phone in your pocket: vibrations seem to have been, and notifications – zero.
