I have always felt family members who have passed away, I feel them around me and sometimes I 'hear' them. Very rarely have I physically seen them, but I have often seen them in my mind's eye, as it were.
I have only in recent months felt my guides (those not related to me) and only 'saw' one of my guides a week ago and he had some interesting things to say.
So that's me. How about you? What different ways do you percieve your guides / loved ones? How do you know when they are with you?
