aronaya,
Hi,
Attachments know no distances. As we might send Reiki to someone 1\2 way round the world so too may an attachement travel (though the energy behind it may, of needs, be significant). Or, it may simply go from our thoughts or our feelings or our intentions into one or more of our energy bodies.
:)
Sleep well, dream well, be well (ie, Wake Up!)
Cheers,
RC
