Has anyone else felt their stomach jump?

Brenda
Hi! I'm 15 weeks 5 days pregnant. The last few nights as I'm starting to fall asleep my stomach jumps. It only lasts for like a second. It kind of feels like the jolt you get when you dream you're falling, only is contained to just my belly. Is this my little one kicking? It's very abrupt, but noticeable. This is my first baby so I don't really know what a kick feels like yet, or how soon/often I should be able to feel it. Thanks!
