Telepathy is common between twins, especially in distressing or frightening situations. This work draws on the numerous testimonies, but also scientific research, to prove that a very strong connection exists between twins. It is among twins that we can frequently observe phenomena related to the transmission of thoughts, but also of emotions and physical sensations or even symptoms. Absorbing and well documented, this work offers us a complete critical analysis of the work and hypotheses concerning the paranormal powers attributed to twins in particular, and the phenomenon of telepathy in general.
