Possible Help... From A Relative I Never Met?

So my family (we've got strong Irish blood on my dad's side, if that tells you anything - pretty superstitious) always has these weird little experiences. I, of course, thought it was a load of crap until this particular experience occurred. Now, I'm not sure, but I'm also kind of worried that I'm just going crazy. This happened a year ago, and I haven't shared it with anyone, though I've been thinking about it an awful lot. I've decided to just throw this up here and see what others think.

Background, which will all come clear in a minute: I can barely hear at all out of my right ear; I enjoy reading and I'm a bit of a flirt; I'm an actress and I was in a play at the time this took place. This play was called "Our Town". My character, the Stage Manager, usually is played by a man, but for some reason the director decided to cast me, a female, in the role. Within the play, the Stage Manager is both narrator, guide to the audience, and sort of Father/Mother Time.

I was having a LOT of trouble with the character, to the point that it was stressing me AND the director out. Not good. The director suggested I make a background for her, etc. I decided to name her Priscilla. Priscilla just fit her. My castmates insisted she shouldn't have a last name, but I liked the last name "Baker" - "Priscilla Baker" just has a ring to it, doesn't it? I decided that she'd enjoy watching over people (hence why she became The Stage Manager, who is basically the town's immortal historian), liked kids, enjoyed baking and reading, et cetera.

I was discussing the play with my dad, mentioning my new name and personality for the character. He commented, almost offhandedly, "Actually, you had an Aunt Priscilla." Well, actually, no, I didn't know that. I knew I had an Aunt Maggie and an Aunt Celia, but no Priscilla. "Yeah," he continued, "Great-aunt, really. She died some time ago; you never met her. Loved kids, loved people, loved to bake..."

Now, that freaked me out a bit. A week or so later, my grandmother called for whatever reason, and the phone started making the rounds through the family. When I got the phone, we chatted for a bit, she asked about my play, and I mentioned Priscilla Baker the character, and how I'd never heard about any "Great-aunt Priscilla". She corrected me: Priscilla was HER aunt, my father's great-aunt, and MY great-great aunt (no wonder I'd never heard of her).

She proceeded to tell me various things about Priscilla, including the fact that SHE was deaf in her right ear, that she loved to read, and even after she went to a sort of retirement home, she enjoyed winking at, waving at, and otherwise flirting with the construction workers who passed by her first-floor window. She even confirmed the fact that Priscilla loved baking, elaborating on how she liked making stew for her crazy Irish family. My grandmother also mentioned that Priscilla was a kind woman, someone who was not just a mother but a very protective figure in the lives of her husband, children, and those who knew her. She loved life, my grandmother concluded.

So... The similarities between me, the Priscilla I'd created, and my great-great aunt really freaked me out. However, I did seem to get hold of the character very well after that experience.

Opening night happened, and during the last two minutes of the second act, my character gives a monologue about weddings. I had very specific blocking (blocking is where you are supposed to move on the stage and when you are supposed to move there). I had to say a line, walk a few paces to the right while delivering another line ("...every once in a while..."), pause on a very specific spot and say the closing line for the act ("it's interesting."). All went well until I started to walk to the right.

I got a deep chill and someone RIGHT in my left ear told me, very calmly, in a low voice: "Don't do that, dear."

So, I listened. I stopped on a dime - stopping my pacing WAY before I was supposed to. I know this sounds ridiculous, but I didn't really register it as out-of-the-ordinary in that moment right after it happened. I continued with my line: "... Every once in a while..." Pause.

Right on cue, a light screen crashed on where I was supposed to be. I would've been knocked out for sure if I'd been there. THAT is when I freaked out. I got chills running up my spine. I was completely losing my head, so I basically rattled off the rest of the line ("it's interesting!") and that was the end of the act. Everyone was asking me why I didn't cross and saying what a good thing it was. I kind of just nodded and smiled - but didn't tell anyone (because, frankly, I didn't want to sound insane and I didn't know what I thought of the whole thing. I STILL don't.)

I'm not sure if this is a... Good thing or a bad thing. I mean, on the one hand, I might have some connection with this great-great-aunt of mine. On the other, I might just be a bit crazy. This seems to have opened the floodgates for a bunch of little things...

Yeah. So, there we are.

Basically, I'm hoping someone has had a similar experience and can help me out as to WHAT, exactly, this particular experience was/would be called - if anything at all. If there is a logical explanation (besides coincidence... I don't know, I'm just having a LOT of trouble accepting that one for some reason) please help me out here. I realize I might be a little fuzzy here, so please ask if you have any questions.
