ie. if you grew an extra limb would you be able to control it independently and feel that it was there?
Im guessing yes, i think i’ve seen a few anecdotes of people who have transformed to varying degrees.
Although im sure it would take quite some effort.
Well. This is another thing that is different with everybody. At least I think so.
Every human has only two legs.
In dream, if you create a third leg, your sub concious will make it work like it would think how it works like. You cannot know how you feel like, until you try it yourself.
