There could be a whole number of possibilities.
It could very well have been the
Phantom, or the
Wraith ... or indeed, the
Ghost. It may also simply have been my old
Nemesis casting a jaundiced eye over the latest goings-on on here!

(I'm pretty sure it wasn't the
Mekon as he was here with me at the time)
On the other hand, it may have been one of our Dear Departed Friends who have gone on ahead of us, to the Other Side (desperately trying to make contact, perhaps).
You know, Tony ... that Big Biomed Workshop in the Sky. As you may recall, I have already reserved my own place there ... at the back, near the window (next to the computer). Ha, ha.
