All names are fake

Okay. My friend, let's call her 'Jane' and her sister 'Ann' passed away a few months ago in an accident, and no one got to say goodbye.
Last night I had the saddest yet happiest dream. Here it is:

Everyone from my school had gone to a Halloween party. I'm in line waiting to get some punch. I look behind me and there's a girl who looks like 'Jane'. In front of me there is a girl who looks like 'Ann'. I knew it couldn't be them because they're dead, but I look at the girl in front of me again and she's smiling. That's when I realize it's actually 'Ann'!!
She starts to fade away.

Quickly I look back and the girl behind me smiles a little. It's actually 'Jane'! I was about to cry in the dream and I had this huge smile on my face, and 'Jane' starts walking away, fading as she went. I go and tell 'Hannah' what I saw, and she looks back to where I point and there's a faint image of 'Jane'. 'Hannah' smiles a bit and 'Mackenzie' does the same thing. 'Jane' smiles back before completely fading away.

When I woke up there were tears on my eyelashes, like I really was going to cry like in the dream. I'm superstitious and think that this might be their way of saying goodbye to me... Does anyone think this dream has some special meaning to it? I wouldn't be asking this, but I'm just really sure it's a special dream and want opinions as to whether or not it's special or if I'm just a lunatic. Be HONEST!
