Wilderness Man-Made Travel Diary

I woke up unemployed and trapped in an abandoned wooden house in the mountains. A diary left by a previous person was left in the house. The owner of the diary escaped from the city and weaved a fantasy dream of artificial time travel for himself. He imagined his mobile phone as an omniscient system, lived alone in the mountains and forests, and performed a simulated time travel by himself. But is it really that simple? For him, it was just a simulation of self-deception, but for me, it turned into a real immersion in the wilderness. The mobile phone that served as the "system" disappeared out of thin air, and the person who wrote the diary was nowhere to be found. While I was struggling to survive by keeping my diary, I was trying to figure out why I was here.
