I would think so. Awareness being equivalent to existence.
Who, what, where, when, how, why... these are all mutables, to some degree. Perceptions change. Objective reality seems quite mutable also. I cannot claim to know exactly "where" one ends and the other begins but I think it is not a matter of absolutes. I feel I am part of an objective multiplicity, in constant relation with my environment and in some sense it and I are one.
What do you think?
