Oh yeah. Extremely narcissistic, controlling, 'better than you' type of person. Used to let me recover for a couple of weeks then stomped me again. That whole experience completely destroyed my daydreaming experience because in my imagination everything was rosy with unicorns, when it was toxic as hell in real life.
Especially with empaths, they can sort of take over your mind for a while. I had the same experience in the past, although it was definitely distinguishable from the daydreaming I knew, which was more often just activated because of boredom at school or as a "passive pastime" in the train.
The word "infatuation" says enough, especially if we're talking (young) adults, and not the kind of puppy love we expect from teenagers. If you're an adult and you feel infatuated, you might mistake that for love, then check if you're dealing with a narcissist or other cluster B disordered person, and also see if you yourself are an empath or highly empathetic.
