I've been wondering what our deceased loved ones know about us. Are they aware of the details of our day-to-day lives, or do they just perceive general feelings of happiness, sadness, pain, etc.?
Do they share our joy, get angry or frustrated with us?
Its been my experience that our deceased loved ones do know about us--even those who lived and died long before we were even born or even thought of! My husbands great great grandmother came through for me in a psychic reading, and has appeared to me a few times as well, and seems to know what is going on in our lives. she seems to like me,

and I was told, she is watching over me, which is a comforting thought.

she was an interesting lady in life, (I found out in my genealogy research).
Also, my grandmother and other relatives came through before my niece was married--to remark that they would be there at the wedding. They didn't really "approve" of whom she was marrying---(Long story) but they did tell us that he was going to be very good to her, and so they were happy for that). So I let my niece know they were all coming, (not about them not being thrilled with who she was marrying though) and she had a candle there on the altar- in honor of all the deceased relatives from both her and her soon to be husbands side).
My maternal grandmother and my maternal aunt and my dad - come up to me often, as do other deceased relatives--and they seem to always know what is going on. They often come to tell me what is happening with family far from me, so I can be in touch with them, which always makes those family members laugh. Once my father fell and had to be taken to the hospital via ambulance-and was bad off. My nanny came to me at 2am and woke me up and told me. (he had fallen right about 1:45 am! So, I called at I think 7am-and my family confirmed it, but surprised that I already knew.
Also, my inlaws are always in our home with us. We have pictures in a collage frame of my inlaws when they were babies, then dating and through out their life. My mother in law thinks it is so funny that we did that--and sometimes not so sure she likes all the pictures of herself in my living room. But, it brings her to us often. And, both the hubby & I look at it daily and talk to them.
I always tell my clients after I do a psychic reading, that your deceased loved ones are always around you. They may not be able to appear to you--or have you 'hear' them, etc. but, they ARE there. It does help them too, if you talk to them (out loud or telepathically) and I encourage everyone to do this on a regular basis. I do talk to mine all the time, and those whose pictures are hanging up (we have a wall with a lot of ancestor pictures too), whenever I am cleaning, dusting the pictures, or just happen to walk past them. I believe that this helps them to make contact with us too.
So, if you need to "talk" about something important, or just want to remember them -- whether or not you really 'knew' them in life--DO SO! They will do their best to make contact with you--so also be 'aware' of things, but always know - they are around.
also, good post and yes, JCWIrish!
