The feeling slightly lighter could be simply yourself drifting towards sleep.

The numb feeling in your right arm - because you're lying on it?

And the coldness - that's a sign of relaxation.  I find I get those chilly sensations in the centre of my body when I relax, although I don't necessarily feel cold.

Next time keep your eyes closed and make sure you are in a relaxed position, with your limbs not squashed!
