Remembering more dreams is one of those PR side effects that they don't really seem to tell you. I remember about one dream a night these days, and I hardly ever even PhotoRead/Activate books! Well...about 4-5 a week generally, but I've been taking it easy lately.
The more you PhotoRead and activate, the more your mind will be active in developing a link between your conscious and subconscious mind. That's what PhotoReading does, it's bringing the information foward, for you to access at a greater level. The more you PhotoRead, the faster and easier it will become.
Your brain is like a muscle, the more you excersise it, the stronger and better it will become for your own personal benefit. There's way more benefits than just the dreaming parts, but it can enhance general learning and memory.
In other words, if LSC wants to name all of the features/benefits outside of the speed of this thing: they'd probably run out of time, money, or space to advertise it all. That's how good the system is, IMO.
