A few incidental details.
"Quasi una fantasia" doesn't mean almost a fantasy (unless you are using poor, unidiomatic online translators!), it means in the manner of a fantasy or as if a fantasy.
It wasn't dedicated to his girlfriend, it was dedicated to a pupil who unfortunately for Beethoven wasn't his girlfriend.
Regarding the performance itself - the above points may be pedantry, but this is more important. Your rubato is totally excessive and detrimental to the flow of the music. It is similar to someone giving a speech and tailing off almost to a standstill before restarting again. All it achieves is to distress/confuse the ear and the performance (which other than that is reasonable enough) would be greatly improved by a less in your face rubato. The places at which you deploy rubato should also be correlated with points of structural and/or harmonic importance. Sometimes less is more.
Regarding the representational content of music, I don't propose to take part in this debate as I'm afraid I have more important things to do

However I will state my position, which you can take or leave as you will. Equally, if you wish to maintain your position, one which appears to be formed from a starting point of untrained musicianship, that is your prerogative but you will have to accept that you are going to either be not taken seriously or it assumed that it is a peculiar manifestation of trolling, particularly as you appear to be claiming to have a power miraculously present in you but apparently not in other musicians.
To my position - all music is either representational or abstract/non-representational. When music is representational, what it is suggestive of can often be inferred from the score. Composers are usually intelligent, cultured people, often prone to literary allusion in the title (Liszt being a good example), or suggestive dynamic and other instructions. Familiarity with a composer also enables inferences to be drawn from details like key signature (C min in Beethoven = anger, F# maj in Liszt = religious ecstasy). Similarly, familiarity with a composer can lead to further understanding of interpretative details: it is documented that the opening of the Hammerklavier represents "Vivat, vivat Rudolphus"; Beethoven has also placed words in his music when he wishes a specific idea (for example the op.81 sonata). To me, the triplets of the Moonlight are a rowing boat upon the moonlit water, but I am being conditioned by the title Rellstab gave it. Equally Tovey said they were, quoting from Wordsworth, "Rolled round in earth's diurnal course/ With rocks, and stones, and trees." Ultimately, in the absence of clear indications, it means what you want it to mean, and if you perform on stage, just be convincing about it.
