Telepathy is pseudoscience.
I think you are referring to the phenomenon of telepathy, which can be defined as
[T]he purported transmission of information from one person to another
without using any of our known sensory channels or physical
and you ask whether telepathy is a scientifically established phenomenon.
Telepathy in general is dismissed as being pseudoscience (Jogalekar, 2013) as it has been debunked in various scientific studies (e.g.
Ayeroff & Abelson (1976)).
Likewise, dream telepathy is considered pseudoscience. It was reportedly first documented by Freud in the 1940s. Freud founded many other pseudo-scientific concepts, including psychoanalysis (Jupp, 1977). Ullman & Krippner from the dream laboratory in Maimonides Medical Center in New York City claimed they had proven the existence of dream telepathy in the 1960s and 70s (e.g. Krippner & Ullman (1970). However, the studies were rightfully challenged. For example, many of their studies were based on a few or even on single subjects (e.g. Ullman & Krippner (1966) and Krippner & Ullman (1970)). Indeed, more recent studies have failed to replicate their findings (e.g.., Belvedere & Foulkes, (1971) and Hearne (1989)).
