Feel myself about to of/ feel myself to do

1. And even after I knew he'd passed, I could still feel him, feel myself about to move toward him.

2. I'm not sure if I should ask for help as I feel myself about to drown in my floor.

Q1) I just stumbled upon the above sentences on Google books, but I really doubt whether "feel myself about to move/drown" is correct English. (I think it's correct)

Q2) If they're correct English, is it also possible to say "Feel myself to move" and "feel myself to drown" without "about"?

(I think in this case, it's wrong to leave out 'about")

Q3) And I wonder whether "feel myself to have become/been/lived/arrived" and "feel myself to have very little latitude" written in the below examples are all correct English. (To me, they seem to all sound natural and to be correct)

3. Certainly our friendship has catalyzed my transformation into the Mediterranean person I feel myself to have become.

4. I feel myself to have been peculiarly fortunate to have lived through, and taken some part in, so exciting a transformation of my profession.

5. I feel myself to have arrived on the very banks of Jordan

6. ..and therefore in printing this report, I did feel myself to have very little latitude indeed as to permitting any alterations in the words of the report.

Q4) Is "feel myself to want" also correct English?

7. By reading only six hours aday, I shall gain in the course of a twelvemonth a great deal of instruction which I now feel myself to want.”

Please answer all the four questions one by one, because I want to know all of them exactly.

Thanks a lot for your help in advance.
