Time in non physical worlds

[majour ka]

Happy haloween 

Theres often talk of time not existing in non physical worlds, ie a costant now. But i believe that people in spirit for example must have some concept of time, for example when i have astral travelled and have had telepathic conversations with those in spirit, it is comunicated as thought but is it is recieved in my mind as string of spoken words which in theory takes time.

Also and i realise this is open interpritaion but if spirit didnt have concept of time how would they know what time to turn up to communicate with a medium at a reading or sceance for example?
