Sleep Overhaul Mod currently adds a Sleepy Head Trait for sims who want to experience an active dream life. Sims will have emotional dreams based on their trait.
The experimental food found at restaurants from the Dine Out GP including the Maxis-made Chez Llama is both cool looking and some of your Sims may even enjoy it. If you have a level 5 cooking skill, you can learn to cook it themselves just by eating it. Problem is, to cook it at home your Sims need to buy their own chef station which is huge and expensive. Who wants to buy that just for some weird looking food? Well, now they can cook the food they learned to make by using any oven or fridge at home thanks to the wonder of mods!
