When you physically meet someone, you meet him or her and he or she meets you. This appears evident. But are you really sure? Are you really sure you’re both meeting?
Is it only you who meets with the other or both? Do you really meet that person or is it someone who looks like him or her, who belongs to a parallel universe, who is a projection of a part of you, a spirit, a dream, a vision, or hallucination?
When you communicate with someone via instant messaging or social networks, you communicate with someone and they communicate with you. This is evident too. But are you really sure? Are you sure there is truly mutual communication, that the person in question is really that person or someone else, etc.?
When you think of someone, do you know if he or she is thinking of you?
When you dream of someone, do you know if he or she is dreaming of you?
These are just questions, with no answers.
All this so as not to take things for granted and also to introduce a quote by Jorge Luis Borges.
“Who is dreaming of whom?
I know I am dreaming of you
but I don’t know whether you are dreaming me. […]
But don’t you see that the important thing is to discover whether there is only one dreamer or two?”
