i did something pretty weird last night

so i just broke up with my long-term girlfriend and im working nights atm. been so stressed out and tired all the time that i really havent felt like going home to my empty apartment after work. ive been staying at a motel nearby, kind of as an excuse for not having to deal with things there but also cuz its just easier right now. anyway last night i met this chick at a bar, pretty sure she wasnt even that into me but whatever, i asked her back to my room and we ended up hooking up. it was wild though cus while were doing it i started whispering all these weird things about how im this super rich businessman or something with a whole secret life, like an undercover cop or something else totally different. i dont know why but it felt good saying stuff like that to her. it made the sex feel so much more intense, even though shes just some random person i met at a bar and wasnt my girlfriend. im not sure if its because im stressed out about everything or what but honestly the way she responded turned me on even more. so now im really confused after all this. am i totally messed up? is it normal to get off being someone else entirely when youre with someone? ive never felt like that before and i dont know why it happened last night. anyone else ever do something like this?
