She also asks: “Can my friend who passed hear me when I talk to her?”

She will not likely hear you as a discarnate spirit who is earthbound, but that will change once she finally reaches the light, then any thoughts you have of her will get her attention instantly and her consciousness will come to you automatically to see what’s up and to be with you, at least for a moment, to check in and see what the nature of the outreach is about, whether it is just a fleeting thought or a stronger desire to say "hello" and perhaps feel her presence in some way. That can well create the opportunity for some form of communication, if only an inner knowing the friend is nearby and sensing her energy in some way intuitively because it will unfailingly be the case that the bond that was created will continue to be honored as long as this is desired by both parties, so the two will stay connected indefinitely and will be sensitive to one another and their energies.
