Take any small signal NPN transistor.
Explain your result.
Clue - you cannot break the laws of Physics, even though it appears that's what's happening here :-) - but you do need to KNOW them.
The result you will get is: -0.35V. (NEGITIVE!)
If you use a metal transistor you can open the case and _SEE_ what happens. The reverse-biased junction produces light, and it causes the other junction to produce electricity(all those junctions are silicon solar cells, after all!).
I doubt if your spice models accounted for this. But even if it does, "Simulations are doomed to succeed."
