I could have an explaination for that (all of it is hypothetical). The human brain is suposed to generate quantum energy on a small scale, as it is generated it is dispersed after some buildup. However, this dispersion patern of the brain can lock up; when this happens the energy is all released in one big burst, the bust has a chance of connecting one or mre of your senses to someone or something else or the opposite, projecting one or more senses to somone else. Qauntum energy can penetrate space and time so someone who got smashed by falling debrese on that day hours later could have had a big lock up from stress causing elevated levels of brain activities, his burst could have projected his senses over to your friend.
