I don't know, but would listening to music. Such as on the radio. Effect if you remember your dream? I don't turn the music onto full blast. More or so medium-low. The music goese from classic to modern. 'Country' to 'Rock' over night. So when I wake up the first thing I hear is a random song or radio advertisement. Would this effect if you recall your dreams?

I use to recall dreams very well, and that was befor listening to the radio. Then I started to at night. No change, till recently? Thus why I'm asking. I'v been dream recalling for a year (Though it hasn't stayed very constant. One month I'll be writing in my dream journal. The next month I won't) and started listening to the radio at night this year.
