You can return to your dreams? Mine just end when I wake up and then I wind up dreaming about something stupid like the kids film Open Season or a 5ft wide pizza made by a native american man.
I can do that sometimes. Especially when I'm semi-conscious that the dream is too interesting. I can muster the will to continue it. But I need to immediately get back to sleep seconds of waking up, while your brain is still in a sub-conscious state, or else it will get lost.
Dreams are powerful things. I've always suffered from intense night terrors and hyper-realistic dreams that I nearly always remember ever since I was little, and at this point I've come to greatly enjoy them. Like the thought of not dreaming or having nightmares is scarier to me than anything my mind has thus far produced, because all of my best ideas come to me while I am dreaming. They are very precious to me, and I wish that we'd develop technology like what is found in the Final Fantasy: The Spirits Within film on how to record dreams and view them as a visual media.
And I am rarely in my dreams as a participant. I am always the audience, watching a cast of characters play out a cohesive story. Whenever I do find myself in the dream, it's always one of three types: It is always either extremely scary and based on something spooky I watched earlier, a dream about my job (a stress dream) or with my significant other doing something dumb and romantic.
But I too often force myself to go back to sleep when I wake up so I can pick up the dream where it left off. And since I lucid dream, if something is too dumb or doesn't make sense, I can adjust things to make it more interesting, and if a dream DOES become too spooky for me to handle, I make myself start screaming in the dream, which will make me wake up IRL. Handy little eject button that I discovered I had when I was getting chased by Dementors shortly after the third Harry Potter book released back in the day and I had spent a whole day reading through it. Woke up screaming 'EXPECTO PATRONUS' and realized I could actually escape when things got too scary for me to handle.
According to my SO and others, I talk and move a LOT in my sleep.
Anyway, long comment is long. Just been thinking about dreams and sleep lately and this made me want to ramble about it.
