Over the past two weeks, I’ve come to a conclusion; there is no more deeply disturbing experience than falling asleep in your own body and waking up in someone else’s.
This time I’m a fleshy, middle-aged woman, lying in bed. Women are the worst.
In this one, "I" doesn't come off as much of an offensive jerk as "I" did in the first one. You introduce a situation immediately which is interesting in the first sentence, which is a positive.
The second sentence is still judgmental and jerkish (fleshy is not an endearing term, particularly to a middle-aged female reader), but it starts showing me the character's attitude immediately, which is also positive.
The last sentence steps on the line with offensive, but some characters are offensive in their beliefs and are still interesting to read, so that's not necessarily so bad. Depends on if that's truly what you're shooting for with this character or not.
However, you do have more emotion in this bit, there's more for the reader to react to (positive and/or negative) than before. I might continue reading this one, whereas I would not have continued reading the previous one. Whether or not I finished the first page would depend on what followed this opening.
