Baby sleep crawling...?

Guys, my son is almost 8 months old and he’s been doing this odd thing where he’ll almost “wake” in his sleep and get on his stomach and crawl. This started about a week or two ago I wanna say. He’ll usually crawl towards my boobs or the tv remote. But once I grab him and lay him back on his back, he goes right back to sleep. Just like nothing ever happened.

He’s also been very hard to get to sleep. He always has to be on my boob lately. Anybody wanna guess on what’s going on or have experienced this?
