I agree with naomi.
As there are energy forms out there we do not yet understand and may well involve what could be termed telepathy - for example the ability of animals and birds to use sonar and navigation systems....
If we look back, how did our ancestors feel about electricity - they could see lightning, the Northern lights, St Elmo's fire, feel static etc but couldn't explain it.
I think it may be possible for some form of energy passes from us to the medium - and this is not per se spiritual....
