How Strange

I sat by my desk doing nothing in particular when I began to fiddle with the pages of my notebook, and then I noticed something strange. I haven't had any experiences worth recording for quite a while now but... I did find something interesting in my notebook. I have no idea where it came from. Could I have written this down myself, while being in a half-awake state of mind?

I'm not sure what these are. They seem familiar somehow, some sort of code I suppose? I have no idea what it's called though (Mary, help me!), I can feel it at the tip of my tongue. But I think this looks way too neat to have been written by me while sleepwalking. Then again, what do I know.

As far as I can tell, the dots and lines at the top are; ... . . -.-- --- ..-

While the rest is;
----- .---- .---- .---- ----- .---- ----- -----
----- .---- .---- ----- .---- ----- ----- -----
----- .---- .---- ----- ----- .---- ----- .----
----- ----- .---- ----- ----- ----- ----- -----

----- .---- .---- .---- ----- ----- .---- -----
----- .---- .---- ----- ----- .---- ----- .----
----- .---- .---- ----- ----- .---- ----- .----
----- .---- .---- .---- ----- ----- .---- .----

I hope I got to write them all down properly. I'm not sure what to say about this; does it mean my so-called condition is getting worse...?
