Start walking

Smoke probably means people, so you pick up the spear and start walking in that direction. Unbeknownst to you, the sheep's eyes follow you as you leave.

Walking through the field you notice that while you felt like you just closed and opened your eyes for a second, your body does feel completely rested. In fact, you feel pretty great. This hike up and down the hills that would normally have tired you out, goes by with ease. The rest of the herd calmly avoids you as if they're not at all surprised to have you in their midst, or as if they are sheep content to eat grass on a nice day, depends how much you wanna read into it.

When you reach the top of a particularly high climb, you actually get to look out at the area around you. Behind you and on the left there isn't much to see, just hills and sheep. Not far to the right you notice there was actually a dirt road. Previously obscured by the hills, it would have provided a much easier path.

Guess I'll remember that for the next time I wake up in the middle of a field.

More importantly it seems your decision to follow the smoke has paid of. Not much farther in front of you, there is a small town. You can't see much from this distance, but it looks like a pretty simple, though busy place. Probably somewhere quite rural. You can't distinguish much, but there are a few figures going about their day.

Hopefully they can provide me with some directions, or better yet let me call someone to come pick me up. Or they will call the police on the crazy medieval person walking around with a big ass spear.
