Future Shock (1970) by Alvin Toffler

Alvin Toffler argued that society is undergoing an enormous structural change, a revolution from an industrial society to a "super-industrial society". This change overwhelms people. He argues that the accelerated rate of technological and social change leaves people disconnected and suffering from "shattering stress and disorientation"—future shocked.
To follow transient jobs, people have become nomads. For example, immigrants from Algeria, Turkey and other countries go to Europe to find work. Transient people are forced to change residence, phone number, school, friends, car license, and contact with family often. As a result, relationships tend to be superficial with a large number of people, instead of being intimate or close relationships that are more stable. Evidence for this is tourist travel and holiday romances.
Many goods have become disposable as the cost of manual repair or cleaning has become greater than the cost of making new goods due to mass production. Examples of disposable goods include ballpoint pens, lighters, plastic bottles, and paper towels.

Simulacra and Simulation(1981) by Jean Baudrillard

Simulacra are copies that depict things that either had no original, or that no longer have an original.[1] Simulation is the imitation of the operation of a real-world process or system over time.
Simulacra might explain the feeling you had about the wedding.

HyperNormalisation (2016) by Adam Curtis

It shows that what has happened is that all of us in the West - not just the politicians and the journalists and the experts, but we ourselves - have retreated into a simplified, and often completely fake version of the world. But because it is all around us we accept it as normal.
But there is another world outside. Forces that politicians tried to forget and bury forty years ago - that then festered and mutated - but which are now turning on us with a vengeful fury. Piercing though the wall of our fake world.

My dinner with Andre (1981)

See, I think it's quite possible that the 1960s represented the last burst of the human being before he was extinguished and that this is the beginning of the rest of the future... that from now on they'll simply be all these robots walking around feeling nothing, thinking nothing.
And there'll be nobody left, almost, to remind them that there once was a species called a human being with feelings and thoughts and that history and memory are right now being erased and soon nobody will really remember that life existed on the planet.

We are forgetful children led by invisible hands towards horrors without words, for reasons unknown.
