Don't forget that it would take longer to read a book in your second language in any case. Part of what you are doing is learning English as you read.
I didnt had still this whole "words sucking into my mind feeling" , should I ?
No, you won't have a feeling like this. While PhotoReading you can affirm your purpose, affirm the ability of your mind to absorb material non-consciously, and you can chant a number or something. Just don't let your conscious mind (a) try to read the material while you are PhotoReading or (b) try to doubt that PhotoReading works--this latter would shut down the non-conscious processing at least to some extent.
Nor I had dreamed about it or have intuition on that subject...
Having intuitions, which might be a kind of "direct learning", comes later, after weeks of practice. Results vary from person to person. You can practice dream awareness, which is discussed in the book.
Finally note that we know how to PhotoRead anyway: we are always absorbing information non-consciously and sometimes using it: PhotoReading just does it deliberately and cultivates a new degree of conscious/non-conscious cooperation for learning in this way.
