This is probably a classic experience, but I want to share my feelings about "traveling" in time
I'm in the past, in "non-existent" time, and in the future, but not in the present.
When I'm in a memory, I feel everything as if it's happening now: I feel the wind, the sun warming me, I hear sounds, I sense distant memories. Everything seems alive, colorful. My memory is very bad and all of this is also made up, but it is still more vivid than the present time.
In reality, I feel almost nothing and it doesn't seem real.
By "non-existent," I mean memories that never existed, but they still feel very real. I look at other people's photos and feel like I'm there. I can hyperfocus and spend hours looking at photos on Pinterest, living a life that's not mine. This time and memories do not exist, but I seem to live other people's lives in an indefinite time.
I'm in the future where my friends left me, where my relatives have died, and I've become indifferent to my hobbies. Sometimes I see what will happen after I die. I see how things will remind me of ex-friends, how the apartment will change when a family member dies. It's as if I'm already there. As a child, I cried for those who were still alive.
But my present is empty.
