here's a random story
I kept going to sleep in my new place and shortly before falling asleep i felt my legs start to shake underneath, as if the building was shaking. This happened maybe a dozen times at least. I didn't think much of it as they often explode bombs around where I live which makes the entire ground shake. But I never stopped to think that they only do this during the day, they never do this at night. And when they blow the bombs the entire building shakes, there's a loud 'bang' and the window shutters a little.
I also didn't classify my legs shaking as 'obe vibrations' either as it was just my legs that shook, and i thought in an obe vibration the whole body shakes.
Now i'm reading my obe book again and it says in it 'sometimes the entire body does not shake, but only the legs shake/vibrate'
classic, all this time i could have had obe's, but instead i thought they were bombing my neighbourhood again, and so i ignored the symptoms rather than try for an exit technique
