That is a great question. But the answer is “no, probably not.” They are no more going to see you suddenly melting into their universe than they will spot you falling into it, walking through a magical door into it, materializing out of a bright light into it, etc.  It is really just your consciousness that is melting and flowing into your DR body anyway. From a DR person’s perspective, you were just lying in bed the whole time. It is quite an inconspicuous way to travel.
