Hi,
I've had a single LD that lasted 10 seconds...
It occured after I was in one place, went somewhere else, then back again.
I did two reality checks,
- Finger through hand
- Covering nose and mouth
And both passed, they went as normal. I still thought "I'm dreaming", jumped in the air 3 times, then "woke" up into another dream.
HAND! (Have A Nice Day/Dream)
