I had a dream that I lived like normal for 6 years

I think I'm having an existential crisis. I had a dream last night that I lived my whole life like normal for 6 years. I had 6 more birthdays, 6 christmas's, made new friends, got married, finished school, went through a few jobs, went to sleep every night and woke up every morning and then last night I went to bed as 25 year old me and woke up again this morning 19 years old. I'm so confused. What if ghat was my real life and this was a dream? what if my whole life is a dream? I can't stop thinking about how when I was little I would tell my mom she wasn't real and nothing was real and everything was just a dream. have I been lucid dreaming my whole life? am I alive?
