Was your grandfather colorful enough that you'd recognize a continuity of interest, temperment or personality?
Well when I knew him he was senile mostly, though he was colorful then

, although he was pretty intelligent just in general aside from that. My dad said when he was younger he was a real "cool guy" who all his friends liked, by cool guy he smoked and drank alot and occasionally did drugs

. I haven't seen Zack more than a few times really so it's hard to compare him to a man I only knew as an older individual. Zack is known to be very sweet and polite so is a person people get along with easily. My grandpa, at least in his old age, was pretty mellow, always struck me as an easy going guy. Despite the age gap I think Zack does look a bit like him but beyond that is hard to say. It would be interesting to see what his reaction was if he saw pictures, videos of my grandpa or things my grandpa used to own.
A somewhat unrelated impression I had once, well also a dream I think, was that upstairs where I live now before I was born in the 1970s there was some college age guy who did drugs and partied alot upstairs. I later found out such a person did live there as I recalled, his name was Seth which is actually a name I've always felt strng resonance with. I also saw pictures of my Dad's time in the military where he was stationed in Germany and pictures of places my parents went when my mom was pregnant and they definately looked familiar so I feel I was picking up prebirth memories or trying to contact them but I don't think they had any announcing dreams.
Most of the impressions I get about other dead relatives aren't presently verifiable. I got impressions that my dad's mom who died 10 years before I was born in 1971 I think was reborn in Germany as a man in January 1983 and my other grandfather who died in 2001 was reborn as a Frenchgirl in 2003 and was just starting school, so I have no current life relationship with them in their new lives. I often get impressions that my other grandmother who died in 2002 is still disincarnate and plans to reincarnate as the child of one of my younger cousins in 2015. At present none of those cousins are married or expecting children in the near future and only one is in a really serious relationship.
I seem to get alot more impressions strangely enough from disincarnate people I don't know yet who are being born now or will be born in the coming years and occasinally messages from famous people I had known little to nothing about prior to the dreams. I've been informed these children, a majority of whom seem to be reincarnating from other planets, will be coming of age in the late 2020s and revolutionize the world in the 2030s. The main being who relayed this information to me, who appears to have been killed(or fought in) in D-Day in his last life, hopes to reincarnate as my child in 2020 even though I never planned on having children. I also sensed someone I know who I still living would reincarnate as my daughter in the same year(twin children)which also seems to be my year of highest personal success(several pyschics independently sensed similar). Aside from that I get lots of impressions of people who I'll know later in life who are alive now as well as their last life and next ones.* But it will be a long wait to verify any of this I guess. But I felt I'd be working with these children being born now in my later life so it will be interesting to see what kind of memories they'll have.
I don't spend alot of time around children but 10 years ago I recall asking some neighborhod children about past lives. One recalled being an alien coming to Earth and the other I very vaguely recall saying something about being a truck driver or driving trucks. I'd feel weird asking most people this though. I'm just shy in general but I've very private about these matters outside those who share similar interests.
*I don't want to hijack this thread so maybe I should start a separate topic but this is the only instance where I may actually have received enough info to verify an individual. I dreamed in January 2005 that a significant person I'd work with in my later life died in an airplane crash in March or May 1979. I later found out there was indeed a major airplane crash on May 25th, 1979 and looked up more about the crash here
http://en.wikipedia.org/wiki/Sheldon_Wax and in the process discovered one of the individuals on the crash was this individual-
http://en.wikipedia.org/wiki/Itzhak_Bentov . Apparantly Bentov was a researcher of consciousness studies and proposed the idea of the holographic universe. It might then make sense his reincarnation would have a high level of awareness and pursue similar studies in this life which could bring us into contact. Not much else to say about that but I found it very interesting.
