Actual
When a consciousness becomes actual it means one of two things it existed and was produced in the past or is being produced at the present time. This compares to potential consciousnesses that could exist or be produced in the future that have never existed before or consciousnesses that have existed or been produced before and possibly can exist again in the future.
The Multiplicity theory of consciousness existence proposes in most of its versions that there could have existed many "actual versions" of each person that exists today in the past. This is limited by the small amount of actual people that have existed in the past on the earth. But we could also include, if they have existed people on other planets. multiplicity allows any number of yous to exist at a time, if the correct structure and functioning is produced.
Some singular theories of conscious existence propose that there are actual versions of you that have existed in the past. Singular theories only allow one of you to exist at a time.
