Am I crazy for thinking about marriage?

Almost a year from when we first met and I had a crazy dream where he proposed to me, now I can’t stop thinking about it. For context my boyfriend and I talked exclusively for about four months before making it official so we’re only 8 months in but I feel we have a strong relationship. He is 10 years older and just turned 30, now after that dream I can’t stop thinking about how he tells me “you’re the woman of my dreams” and says I’m “the love of his life” on the regular. Since he’s older I figured he’s definitely not NOT serious in terms of dating and he talks about our future together a lot, am I crazy for thinking about marriage in the not so crazy distant future? I also wonder if he thinks about it and when would be too soon to talk about it. I especially debate this since at 20(my age) marriage seems a bit soon after some months or a year even but also at 30 (his age) I feel like maybe it’s appropriate timed and maybe he’s even seen as being a little late to getting settled down by his family and society. What do y’all think?
