Be glad you do not sleepwalk, because you might have done that in your sleep.
I had a childhood friend who used to sleepwalk and you when you see it happen, you do not fully realize they are asleep immediately, because their eyes are open and they are doing something that seems generally normal until you address them verbally and then it is quickly realized that they are asleep. It is best just to tell them to go back to sleep.
The night you had your odd dream, I also had one.
I had to go back on my uncle's boat which was a civilianized military craft a little larger than a P.T. to use the bathroom on it.
As I boarded and got to the bathroom, I flushed the toilet and somehow the engine started the anchor went up while I was the only one on it, I had to quickly race up some ladder steps to get the helm.
This was a really, really big boat and as I was steering it trying to miss other boats, knocking out mooring docks, going this way and that way, trying to steer out of the way of closing water gates as well as other water craft, the whole time saying aloud with heartpounding fear "Oh gad...oh shii... oh gad ... ohshi-i... oh gad!!!" repeating this phrase over and over.
Finally, I managed to steer clear of a last closing water gate and got out to almost open harbor but between a rock jetty and the harbor behind me, I ran over a film crew working on a sci-fi film and the crashed space craft prop vehicle in the water they were using to make their movie, breaking it up even further than the arrangement they had for their shoot.
Since I did not wake up in jail, I have it reaffirmed that I am not a sleepwalker like my childhood friend was.
