I am a very artsy person, if you went into my room you'd see balled up pieces of paper and markers, paints, crayons, oils, etcetera, all around my room I can't help it. I recently moved into my sister's room because she has gone off to college, and ever since I've moved into this room its been cold, like really cold. Sometimes I wake up shivering even though I have three blankets on me.
Anyways, it was a normal school afternoon, and I was incredibly tired as usual, so I take out my sketchbook and turn to the last page. I place the marker down on the page trying to think of what to draw, as I'm holding the marker on the paper it starts writing something. "Bonjour," I was distraught so I said "Bonjour" out loud. I was taking French at the time so I said "Comment t'appelle tu?" (What is your name) "Turquise" they wrote. I was really scared then, I didn't know what to do. "quel âge as-tu ?" (How old are you) "Ounze" (11) I was creeped out and as I was about to close the pad my hand MY HAND wrote quickly "Don't go!" I opened it up and was greeted by a smiley face. I found at that it was a she and she died around 1708. She's still with me to this day, and my room is still cold to this day, but at least I can say, I've got a new ghost friend.
As I'm writing this I have a blanket over my shoulders, and a friend by my side, she's like my guardian angel, whenever I'm sad she cheers me up, she does scare my dogs a little, and they never want to be in here, but at least I know I won't be alone through rough times when I need someone.
So I'm going to leave my personal thoughts about what Tarquise may or may not be alone. Instead, I'm going to say that you DO need to learn protection! Whether or not Tarquise is malicious or not is irrelevant.
Think of it this way: Tarquise was able to control your hand, and you feel that she's a good spirit. But what would happen if she wasn't? That's quite a scary thought, no matter who you are, which is why learning how to shield yourself is so important. Besides, if Tarquise is like any good friend, she would want you to be safe.:)
