I have been having trouble with wanting my hand to move to write and the movement lagging behind the thought in my brain. And my hands/limbs seem heavy. As you can see, I can type once I get going. What is this? I have had vertigo and this seems similar in that floating following way BUT, it seems different in the heavy limbs and actually think before it moves. Though not nearly as bad as Michael J Fox, when I watch him...I see shades of what I feel in his movements.
This just began about 5 days ago, it does come and go. Nothing new except a cold.
So, any help?

That would be my guess. Some viruses can alter perception surreally.
