Yea. You could be right in saying That I could be biased. I could have believed them because they are someone whom I know and I trusted them based on their words alone (since I can't actually see ghosts I wouldn't know if they are there or not.).
Anyways, the story goes like this.
We went overseas with the school musical troupe to somewhere in China and we checked into the hotel. We had booked the entire level of that hotel so the entire level only had us.
It was already pretty late when we reached so once we were given rooms we went up to put our luggauges. During this time, everyone was moving around freely so it's pretty difficult to know where each other is.
My friend C, had planned to share a room with another friend D, and her sister. This is what we know.
From here onwards is the story. Whether it is real or just some coincidences is up to you whether you believe or not. As for me, I just feel its too amazing to be just a coincidence.
So C came out of the room after she dropped her luggage and headed for another room (she said she was going to visit some friend from the other group to see if they have settled down.) and so D and her sis came up with her luggage and went past C. Curiously, C asked what D was up to, with her luggage. (which clearly is a weird question to me of course)
D was like... "what the... Of course I'm going to our room! What else?" we were like... ?!?!?! (what's with the question)
So she told us that she saw someone else who looks like her in the room. Before she could further explain, a mother ( a parent guardian) asked us what happened (we were standing there not going to our rooms) so C told her that someone else which we might not know was in the room when she went in. That person ignored her when she called to her telling her she will be going to someone else's room.
So the mother went to check it out with their key. The rest wanted to take a look but C suddenly stopped them, thinking it could be 'something else' since she knew she could see 'ghosts' when she was younger. Of course, we were skeptical. But we asked what she saw, anyway...
So she told us she came up to put her luggage and thought nobody was there because the lights are off, but when she went in, she saw that the bathroom light was on even though it was dim. So she peeked inside and saw a girl combing her hair and her back was similar to D's so she thought it was D. She asked why didn't she turn on the lights but she didn't reply. So she told 'her' that since she's there, she'll leave the lights on and she'll head to Another friend's room for a little while. Then D's sister asked how she looked like... (I suppose it's because C said it looked like her sister...)
So C told us, she had long hair and was wearing a blouse and striking blue pants. And that she was combing her hair. So she could see only her back so she presumed it was D.
Then we were like... Could it be S? (someone else) since they look similar from the back and they are pretty close. But... how could it be?! She does not have the key. And who in the right mind will go to another person's room to comb their hair? but of course there's a possibility..........
Anyways, it was freaking us out and obviously quite a lot of people saw us discussing and came over to understand the situation. We were waiting for the guardian to return and she did. And she was carrying C's luggage. She whispered to C pretty softly and perhaps slowly, asking if what she saw was a girl sitting on a stool combing her hair and wearing brown blouse and blue pants...? C nodded and the guardian looked troubled.
We were like... O.o okay they saw the same girl... So who is she? I nearly wanted to breathe a sigh of relief because someone else could see her so it is highly likely that she is not a ghost. What are the chances of someone else able to see one? Was what I thought. (The others was convinced she is a ghost I think.)
But even the guardian told us that it's best not to stay in that room anymore so she brought C's stuff out and asked her to move to another room. Of course, by this time many others were already crowding around and asking questions. So the mother and C were trying to explain what has been going on and suddenly they fell silent and pushed us and say it would be best to talk downstairs at the cafe and asked the rest to get their luggauges down to the lobby as fast as they can. After querying about it later, C told us it was because the 'ghost' came out of the room.
Anyways, we haven't unpacked so we just dragged our luggauges down. It was around 10pm or so I think... Can't remember very clearly but it should be very late because I remembered looking for another hotel near the area was pretty difficult because of the time. I heard that we got a partial refund from the hotel and we had to split to a few hotels for the night.
This is one of the most convincing incidents that I have encountered. The rest that I've heard are just stories though and more scary, but it isn't as convincing since I have nothing to do with it. Anyways, whether you believe it or not is up to you haha since I don't have evidence to back me up XD
Anyways, I really hope that it is explanable by science.
But even so, I still believe that there are such things as ghosts. >__<
