Do Buddhists see reality as consensual or individual? Do Buddhists see reality as consensual or individual? Are all persons' realities joined in a seamless whole, or is each person a window onto nothingness that can never be seen by anyone else? I am not finding easy words for my question which seems clear to me...

I see two real things (only), that are one: the Void, and Experience. So for me, everything in Experience is one thing, whether I perceive that or not. Yet each is also unique. Are we all connected like fingers on one hand, or more like ants in a colony: each distinct and un-mergeable with the others?

Please provide a reference that I can read. Thank you!

EDIT: I have this well-known quote attributed to the Buddha: "We are what we think. All that we are arises with our thoughts. With our thoughts we make the World." So, my question is:

The word "We" - does it mean collectively, as a plenary (not by assent but in fact), or does it mean each of us individually? The word "The" World - does it mean the common reality, or each of our individual "realities"? Simple, yet subtle.
From Buddhist perspective, phenomenal (experiential) reality is dependently co-arisen phenomena. In other words, experience depends on convergence of a number of factors. Some of those factors are common across multiple cases of perception, and some are specific to an individual case of perception. To the extent that some factors are shared, realities are similar. To the extent that some factors are unique, realities are dissimilar.

This topic is discussed in depth in a very advanced work of 19th century Buddhist philosopher Mipham, called Beacon of Certainty (topic #6). For a more casual read, check out The Prayer of Kuntuzangpo. Also see Lamp of Mahamudra section one, "Ground Mahamudra".

P.S. 

The objects (and subjects!) appearing in each of the realities are not truly existing. But there is only one ground underlying them all. To realize the true meaning of this ground is to be Buddha.

There is an infinite number of valid, internally not inconsistent, but not necessarily compatible with each other, ways to cognize this ground. Although all cognitions (including cognition of the true meaning of the ground!) are construed on the basis of temporarily combined elements (so in this sense no one cognition is fundamentally better than any other), however, since there's a case of being aware (vs. being unaware) of dependently-coarisen nature of objects (and subjects!) of perception, there's a sense in which we can speak of an awakened cognition. Or as Master Dogen said in Genjo-Koan:


  When all dharmas are [seen as] the Buddha-Dharma, then there is delusion and realization, there is practice, there is life and there is death, there are buddhas and there are ordinary beings. When the myriad dharmas are each not of the self, there is no delusion and no realization, no buddhas and no ordinary beings, no life and no death.
