What do the words of the Mahayana Buddhist mean? A Mahayana Buddhist said:

Mahayana Buddhists agree that there other sentient beings exist, that
they have discrete mindstreams, and ingest and interpret reality in
accordance to their own karmic dispositions.
If I encounter you, I believe you are a sentient being, and that you
are not me. But I also recognize that I never interact with you, only
with the impressions of you that my mind has recreated from sensory
contact.
So my experience of you is 'imaginary' in the sense that all I have is
this mental representation that was constructed within my own mind,
using limited data from where our actions and sense systems have
interactions.
But you clearly exist on some level, because you can perform actions
that I did not cause, which means that you are not some kind of
phantom my mind created.

Can you please explain to me what this means.
What does the following mean?

But I also recognize that I never interact with you, only with the
impressions of you that my mind has recreated from sensory contact.

That is, does it mean that when he talks to me, he thinks he is talking to an imaginary person?
Thank you!
Let's say there's a person called George, who is a lay single unmarried man, aged 39, and is strongly interested in Buddhism.
Now let's take a look at other people around him.
Let's say his friend Tom, is of the same age and is happily married with 3 kids. He looks at George and pities him for being single and not having his own family. He thinks about advising George to try more diligently to achieve the goal of marital bliss in the near future.
Another friend of his, Bob, is an openly gay man. He looks at George and thinks that perhaps George is a closeted gay man and that's the reason why he's single and unmarried. He pities George for not being true to himself and opening up to his fullest potential of happiness.
And then there's his colleague, Jim, who went through a bitter divorce, separating from his ex-wife who cheated on him with another man. Jim is very emotionally hurt from his divorce. He looks at George and envies him for having made the right choice to remain single and unmarried.
Lastly, George knows a Buddhist monk by the name of Sadhu Bhikkhu whom he met at a Dhamma talk. Sadhu Bhikkhu looks at George and thinks that perhaps George is single and unmarried because he is considering joining the monastic order in future. Sadhu Bhikkhu is hopeful that more interested men and women would join the monastic order.
So, in each case, Tom, Bob, Jim and Sadhu Bhikkhu, all know the real person George, but they each form a different mental model or mental image of George. When they interact with George, they are interacting based on that mental model that they have created, and not based on the real situation of George.
I believe this is what is meant by the Mahayana Buddhist.
