“[...] [A] person cannot be aware of two scenes, or objects, or percepts within the same modality at exactly the same moment in time (as illustrated by a Necker cube, Gestalt images such as the young-lady/old-lady ambiguous figure, and incongruent inputs into two eyes in studies of binocular rivalry). So it is with pleasure and displeasure. Conscious experience can move at great speed (estimated at 100–150 ms per conscious moment; Edelman & Tononi 2000, Gray 2004), so that it is easy to shift back and forth between alternative experiences very quickly, and to summarize both experiences in a memory-based judgment. In fact, research that specifically limits the time window to momentary experience does not find dialectic representations at single moments in time (Leu et al. 2006, Scollon et al. 2005, Yik 2006). As a result, it very unlikely that pleasure and displeasure co-occur in real time, although people can quickly shift experience contents from one moment to the next, and summarize all of the experienced contents in memory. As usual, it all comes down to precision in scientific language, namely, what one means by ‘at once’ in the sentence, ‘People can (or cannot) feel two things at once.’ The same argument can be made about emotional complexity, or feeling more than one emotion at once (Charles 2005).” (p. 378, Footnote 5).

...and, therefore probably also about “being with myself” and “being with the other” at once.
