Don't know where you heard that because PhotoReading is not reading. In fact 300 words a second is not even considered "reading" anymore.
You don't have to be able to lucid dream to PhotoRead.
If you want lucid dream experiences focus on that.
If you want to succeed with PhotoReading focus on that.
PhotoReading is easier to learn than lucid dreaming.
The experiences mentioned happen occasionally> If you try to chase similar experiences I can guarantee you won't have them. If you let go and see what happens you increase the chances of it happening for you.
