Seattle:
I'll take your opening post at face value for now, rather than assuming you're trying to set people up for some kind of demonstrative "fall" in this thread.
I woke up in the middle of the night, the curtains were moving and I saw the shape of a human behind one of the curtains and although "it" didn't actually speak to me, I felt as it if was trying to tell me something.
Questions:
1. Are you aware of any particular cause for your waking up?
2. What makes you doubt that it was a normal human behind the curtain?
3. Why do you rule out the wind, or similar, as a cause of the movement of the curtains?
4. What gave you the impression it was trying to tell you something? What did it actually do to indicate that it was trying to tell you something?
Now, I don't believe in ghosts but I just want to make sure I understand the scientific method. Something has to be repeatable, right?
Something has to be repeatable in order to do what? What outcome are you looking for here?
The next morning at breakfast several other people mentioned not sleeping well and hearing strange noises and some of them saw the curtains moving just as I had.
5. Did these other people describe "the shape of a human" behind the moving curtains, too, or did they describe just a movement of the curtains? Was that before or after you told them about your human-shaped movement?
6. What reasons did the other people give for not sleeping well? Any particular reason?
7. How did these people describe the "strange noises"? What were the noises like? What was strange about them?
8. Did you also hear "strange noises"? What did you hear?
9. Describe the motion of the curtains that you observed.
I don't pretend to know what was going on...
If you did, presumably you wouldn't be asking for possible explanations on an internet forum.
... but I do believe that we don't know everything...
I think we can take that as given. Why do you think not knowing everything is particularly relevant here?
...and I'm just asking you guys if I might have seen a ghost ...
It seems unlikely, given that the existence of ghosts has never been convincingly established. But we can't conclude anything for sure unless we can work out what actually happened to you. And if we can't work that out from the available evidence, then the question will probably remain unresolved.
...and if science, though the scientific method, might not agree in this particular case?
You think you have sufficient evidence to persuade the scientific establishment of the existence of ghosts? If so, good on you. Please present your persuasive evidence.
