The problem here is not the difference between Sim and aeroplane
I would not rule that out completely. Especially in a bounce the accelerations felt in the sim are not the same you feel in an aeroplane, there simply is not enough space around the sim to do the movement necessary to fully simulate this. People are different, some are more optical oriented, some are more motion sensitive. Although an IFR pilot should be able to ignore both and just work according to instrument indications, in fact especially in a sritical situation you may fall back to your subconsciousnous trained reflexes, and the sim may just train you to feel the wrong thing, finally confusing a bounce with positive climb.
Additionally the criteria used to evaluate sim checks may not be very useful in real life, many feel under time pressure in sim checks, feel they get better marks if they react quicker, are afraid to get poor marks if they carefully analyse the situation. This trained immediate response may not be useful in rare events.
The problem is not the difference between sim and aeroplane, the problem is not to understand this difference and what this means. It is perfectly fine that the sim is not 100% like a real aeroplane, your landing yesterday was not 100% like that today, this is life. We schould just not make the sim the standard.
