Back in the time

DON'T MIND THE VOICE PLEASE! You're a really normal person (or not? It depends on you). You have come home from a long and exhausting day outside. Everyone has annoyed you today and you have no energy for anything. You open your phone, check what's new. The phone buzzes strangely, and then suddenly the living room dims and disappears, and so does everything. You close your eyes, frightened, and when you open them, you see... a city. It looks like a city from seventy years ago. You try to understand what is happening... So like this - your phone has sucked you back in time. Try not to scare people with technology, otherwise they will think you are a wizard.
