Is it normal to dream a lot?

I have been a sleep therapist for 5 years and have studied under the best doctors at MUSC teaching hospital. You dream in a period(or stage, there are four: N1, N2, N3, REM) during sleep called "REM" (rapid eye movement). Every single person on the planet, along with many other animals go through REM. In fact 95% of people go through REM 4-5 times a night, every night, for their entire lives. Each period of REM can last between 5 minutes and sometimes up to an hour and a half, and it is normal to have multiple dreams during each REM period! That adds up to 50 or 60 different dreams every single night of your entire life! But remembering them is another story. It is argued that the better quality sleep you get you remember less of your dreams. It has been proven that if you do not commit a dream to memory upon waking that it disappears from memory. From my personal experience I have formulated this: people tend to remember the one or two dreams they had right before waking up, and have a much easier time remembering them if they wake up directly out of REM, but so far I have seen no correlation between age, sex, race, or quality of sleep and remembering one's dreams.
