Is there a sleep regression around 11 months?

My son for the past 2 weeks has been waking up 2 hours after he falls asleep at bedtime. It won’t be every day, maybe 3 times a week..it’s not food/gas related and he has no teeth that I can see under the gums. It takes him sometimes an hour-hour & a half to settle him back to sleep. It almost seems like maybe a baby nightmare, because he cries like he’s hurt/scared or something. Just trying to figure out if it’s normal around 11 months
