Coffee grounds, time travel, and some dream interpretation...

Okay folks, little reluctant to post about this but its important to me and I figure this is a good place to start... This post is related to dream interpretation, about a reoccurring theme I've noticed over the years and my curiosity \ concern about it.

Warning, its not disturbing or anything but kinda disgusting, nothing offensive mind you or weird but well, I just wanted to warn you ahead of time.

Every now and then, in my dreams, I'll dream that my mouth is literally filling with "stuff." It doesn't come from my throat, or from the outside, it just literally fills with some kind of stuff. In my dreams I'm often very concerned about this and no matter where I am I have to spit it out. It doesn't have a taste really and I never swallow it, but I definitely do what I can to get it out.

Sometimes after I spit it out, and or wash my mouth out with water, it continues to fill up. I don't remember watching it fill but I can definitely feel it. It eventually stops thankfully. I'm never afraid or in pain, just obviously concerned. No one seems to notice, in fact if anything, I do what I can to hide this from whoever is in my dreams.

If I had to describe it, the stuff, the closest substance wise would be, coffee grounds. Now don't hold me to that, but I think I'm pretty close to what it feels like. I don't usually look at it but when I do, I've noticed it was a yellowish color, black, and once green I think.

Just recently it was related to time travel for some odd reason. I traveled back an even four years, was at a school I never attended with some family members, and was upset for some reason. I'm a big time travel buff, if being a buff of TT is even possible, and I think about it semi often for a variety of reasons in a variety of ways. I'd assume I'd be ecstatic if I was able to do so, but this time around I wasn't.

Oddly enough I was going to explain this to a group of people in a class room, the teacher being some kind of scientist. This time the stuff appearing in my mouth was related to the TT somehow and I think the amount meant something, and since there was a lot I was very interested in proving it to the teacher, even washing my mouth out in front of him.

Annnnnway, if this was a TMI moment from a newbie, I apologize. Its just something I've always wondered about and God knows google isn't very helpful. So I guess any assumptions on what it could mean, any parts of my latest dream and or the imagery in general, would be great. But it definitely gives me pause after I have these dreams and I'm endlessly curious about it. Thanks in advance.
