"but I than suddenly woke up, in my dream." - Do you mean you're dreaming within a dream or something like that? I too experience it.

Yes, if I recall correctly, I did wake up within my dream. So like a dream within a dream. I don't really know what that means but it's there nonetheless.
As to whether or not I had hurt someone, yes I guess so, though not intentionally. This was in a time of my life where I was in a very nast breakup as a result of my fears and therefore manipulations. It had me feeling very dead inside and just switched off.
