Sleep Tight Mod for Minecraft 1.20.1, 1.20, 1.19.4 and 1.19.2, is a rebalancing of sorts, as well as an overhaul of the default sleep system for games. Now, sleeping through the night will not always be the norm, and in fact, players will be rewarded for always sleeping in the same bed.
Basically, the creator wants players to sleep not just for the night, but for what it means in reality, adding extra value to the rooms of the houses. In addition, it will also allow players to sleep immediately without setting a generation point.
One of the most important characteristics is related to daytime sleep stages, that is, any player will be able to sleep during the day. This will make certain hours pass, but not the whole night. And beware, it also adds certain dangers and inconveniences to sleep, such as nightmares or bedbugs!
Overall, sleeping should feel much more rewarding (due to the increased difficulty), while still being fun and engaging at the same time, particularly with the new nightmare mechanic. All this without breaking the default gameplay experience, which is essential for many players.
The creator of Sleep Tight has also added sleeping bags, hammocks, bedbugs, the property of home bed (by sleeping 8 times), nightmares or sleep changes. Despite all the above-mentioned features, it is still in an early version of development.
