Mixed Feelings about an Apparition

I wanted to see my grandmother, who died in 2006, third of jan to be exact, it was quite early (well for me), at about ten thirty to eleven at night, I was just laying on my bed facing the T.V. My mum had just emptied her wardrobe, all her clothes were hanging on my wardrobe.

Here's a quick bit of background, on christmas day we went to see my nan in hospital, where my younger brother (we will call Dave), gave my nan a red west ham united teddy, this he in fact forgot, and he got it back after she died. A few weeks later, my mum heard my brother going downstairs, and she followed him, where he got a glass of water, she asked him what it was for and he said my nan, he said she had a nasty cough, so upstairs they both went where my mum found loads of tissues surrounding this teddy, quite freaky I thought, but a couple of months ago my brother lost this teddy.

So back to the story, I'm laying there watching T.V when this missing teddy appears, right on top of the T.V, now I'm freaked and Dave looked over at me, then we both stared back at the teddy, and it vanished, right there, then the dressing gown, on my wardrobe, started to move, like wind blowing it, and of course it was in front of the window, so I closed the window, (the window has one opening on the top), I went back to bed, but the dressing gown is still moving. I check the window closed, I check the door, closed, and just as I climb back into bed the dressing gown flew to the flow, and it rose, like someone crawling from the floor, and there stood, a very tall woman, with grey short but curly hair, very broad shoulders. I realized it was my nan, she smiled at me and disappeared, now, although it sounds nice, but the feeling I got before she appeared, was of an evil one, I was very frightened, but when she appeared everything went warm.

Is this is a sign she is protecting me from something in my room, or is she the evil thing, can you please help me. Thank You
