Does anyone ever have dreams so real, that when you wake up it takes a minute to separate dreams from reality?

Hi, first time poster. I've suffered from nightmares like many of you for a long time. Sometimes things happen in my dreams that look and feel so real (ex. like approaching the toilet in a dream) that when you wake up, it's like the reality is the dream? I can't describe it very well. I'm just looking to see if this is something many or not many people can relate to.
