Hi Alex.
I have to say that I know what you mean. Sometimes I have had parts of dreams come back to me that feel as though they happened two or so years ago. Actually, the weird thing is that I have just triggered one now thinking about it. But it is one I have seen before in the meantime.
I can't think of any reason why it happens. Maybe you are using some deep level brain entrainment? If that's the case it might be an explanation of why you are getting dream flashback.
