I think there may be some subtleties here.  Like many others, I&#x27;ve experienced great sleep in hotel rooms, or as a guest in homes that set me up very comfortably.  That said, I definitely have noticed I remember my dreams much more frequently if I&#x27;m not in my own bed.  Whatever my subjective evaluation of the quality of the sleep, it seems like something different is going on in my brain when I&#x27;m in unfamiliar surroundings.  Maybe the effect shown in this study explains that.
