Holding onto dream objects after the dream ends ... can be a rather weird experience.
I did have a few similar excursions... and even one full blown awake vision (or halucination if someone prefers to call it so). I was sitting and writing and all of a sudden I saw (with my inner eye, or the eye of my dreaming-body or whatever) one HI (both visual and audio). As it came so it went. I dediced to not get all pumped-up with the experience since I wanted to finish what I was writing and when I did, I decided to turn back to what I experienced (that HI). Now things get even weirder. I recalled the image (still sitting in my chair) and audio and gave it now due attention, and suddenly in relation with the HI I had a kinestetic sensation in my belly... and things here went really really weird since I entered a kind of what I might call a "lucid-nightmare" which lasted several days in completely awake state. Why awake? Because I could not fall asleep during the whole experience (a week, to be exact).

Now, not to frighten anyone (it was just me and associations in my brain at the time) with this, as I came to realize, HIs are in any case a kind of dorways into dreams (or might be), so holding onto that image in the awake seems a lot similar to holding onto a dream object (let's say, what I saw was a rather strange DC, yes, human(like) bit strange anyway). With this I can concur with you Royaltramp - there can be experienced rather weird things either with the body or within it.

On another occasion, I held onto a "dream(ing) consciuosness" for quite some time during the day (till afternoon) and I had given a name to that day: the weirdest day in my life. Strange situations arose, as if I was still dreaming but I was out and about.

The thing is, things really start to get strange and weird when one tries (or it happens to one all by itself) to hold onto things of dreams and if they somehow persist into the awake. At least, it was so for me.

Dreams might be illusions or imaginary things, but whatever they are there is a kind of energy in them, there is something there, even in our own imaginations (being "ability" itself, means that it is able to produce some kind of effects, most people would agree that even imaginary feelings (or emotions) are real as reality itself for the one experiencing them). So, it would not be too much of a strech of wishfull thinking to crawl into the direction of a conclusion that dream-objects (holding onto them) can have some effect here after we wake up and hold onto them for some time. Be it healing or sudden inspirations for creative solutions or something else...

Even remembering dreams can be sometimes viewed as a weirdo in itself: relatively recently I had a conversation with a friend who confermed that it was same for him. Namely, remembering dreams is a kind of bringing out and holding for a time onto objects or scenes or whatever of a dream and both he and I have felt the same or similar effects "within" the body, while the dreaming-you (or dreaming double, as it is called by some) is wriggling out of slumber... especially when more dream-memories pop up into awareness at the same time.

On few occasions while I was working with remembered dreams, location in the dream started to mingle in my consciousness with (its supposed) thought of real location in the city itself and for a few moments I was in both places at once, my awareness was as if split between (and at the same time merged with) both awake consciousness and dream consciousness (while at the same time I was sitting in my room, but was not aware of my body, but was concentrated on those two locations, one from dream, another from real world corresponding to it)... It was, a strange experience in itself... since for a few bried moments I was not sure where I actually am?

The point of all this being: one could move in the real world and continue being in the dream at the same time. Or as if in a kind of both there and here but somehow not completely neither there nor here... Completely another question would be could we put all that into some good and productive use each and every time we manage to experience it? Or does it remain simply a weirdo in itself...

I am not sure if these are all on the subject of this thread... but seems to me rather close in some ways.
