There is a thought I have been reflecting on: perhaps the world we live in is a physical dream. We enter it, meet people, form relationships, and become involved in everything happening around us. While we are here, this is our reality. But once we leave, we cannot come back to this exact life and continue where we stopped.
I am exploring this as a philosophical idea. A dream I had brought it into focus for me.
Not so long ago, I dreamed that I met a person. He said, “I have something to tell you.”
I was eager to listen. I felt a strong sense of anticipation, waiting for him to continue. At that exact moment, I woke up.
Now, how do I go back to meet that person?
I cannot simply close my eyes and choose to stand in front of him again. I cannot ask him to finish his sentence. The encounter was there a moment ago, and then it was no longer available to me.
Even if I were to dream of him again, could I be certain I had returned to the same encounter? A similar face or setting would not necessarily mean I had entered the exact moment I left.
This is where I see the connection with the world we live in.
A Dream Is Our Reality Until We Wake Up
While I was dreaming, I was participating in that world. There was another person in front of me, something he wanted to say, and something I wanted to hear. I was interested in what would happen next.
Only after waking could I look back and call it a dream.
Our waking lives also have this quality of involvement. We are surrounded by people, conversations, responsibilities, and desires. We want to know what tomorrow will bring. We make plans because we expect to be here to carry them out.
From within this life, everything feels immediate and important. We have a place in the world, a name, a history, and people who recognise us. It is difficult to imagine being completely outside all of that.
Yet in my dream, an encounter that had occupied my attention became unreachable in an instant. That makes me wonder whether our relationship with this physical world could have a similar boundary.
What We Can Touch, We Still Cannot Keep
By “physical dream,” I mean a world we experience through our bodies, within which we live for a time, but which we cannot keep or return to whenever we wish.
Here, we can touch the ground, hold someone’s hand, and hear a familiar voice. Our experiences have consequences, and our lives are connected with the lives of others. This gives waking life a solidity that an ordinary dream does not have.
Still, solidity does not necessarily mean permanence.
A house can stand for longer than the person who calls it home. A place can remain while the life someone lived there is gone. The physical world may continue, but our participation in it has an ending.
The dream comparison concerns that participation. For a time, we belong to a world and experience it from within. Then we leave, and the possibility of continuing that particular life closes.
Another Life Would Not Be This Life
When I woke up, the person in my dream did not become someone I could visit later. There was no address I could travel to and no way to arrange another meeting.
Wanting to return did not make returning possible.
This is how I understand the idea of leaving our physical dream. Once we go away from this world, we cannot simply step back into the same body, the same relationships, and the same moment, carrying on as though we had only briefly left the room.
Whatever someone believes may exist beyond this life, that exact life is what concerns me here. Even the possibility of another existence would not be the same as resuming this one.
A different dream would not complete my conversation with that person. In the same way, another existence would not automatically restore this particular place among these particular people.
We Always Think There Will Be a Next Moment
Thinking of life as a physical dream makes its ordinary details feel more significant to me. The person speaking to us, the room we are sitting in, and the familiar surroundings we barely notice are all part of a world we currently have access to.
We are accustomed to that access. We expect to see familiar faces again. We expect another morning in which our lives will continue.
In the dream, I also expected a next moment. I expected the person to speak, and I expected to be there to hear him. Waking ended that possibility without asking whether I was ready.
Perhaps this is what the image of a physical dream helps us contemplate: we are deeply involved in an experience we cannot possess permanently.
I do not know what the person in my dream wanted to tell me. But the encounter gave me a way to express this thought about life.
We are here now, inside this physical world, meeting one another and waiting for what comes next. One day, we will no longer be here to continue. And just as I cannot return at will to the person who was about to speak in my dream, we cannot assume we will be able to return to this life and pick up where we left off.
