If you suspect your imagining your reality, join the party. Most won't take the responsibility for it, sometimes maybe what they consider good or positive? For me, I think it was the bad/negative that spoke to me the most/follow the thread. Somewhere along the way, there were clues, and looking back, an overview/shift in perspective very revealing aka third party view no blame, just experience. You can test this by Practicing Presence aka quieting the mind, successful to the degree you have refined that skill.
