Basic rules
1. You will encounter Dream Lotuses in the stage and have the chance to have a Sweet Dream or a Nightmare.
2. If you have a Sweet Dream, you'll need to defeat the Sleepwalkers to awaken the Sweet Dream Lotus. Interact with it to select Dream Omens to enhance your Dream Bubbles, which will also make your Nightmare more dangerous.
3. If you enter a Nightmare, you'll need to survive the trials of the Nightmare. Pass the trial, and the Dream Bubbles' rewards will become real.
4. Your chance of entering a Nightmare increases with every floor advanced in a Sweet Dream until you finally enter a Nightmare.

Dream Bubbles
1. The rewards obtained in Twinightmare are collectively called Dream Bubbles and only become real after you escape from the Nightmare.
2. Dream Bubbles have two attributes: quality and type. You can check the details in the descriptions of Sweet Dream Omens.
3. Starting from Timemark 7 in Netherrealm, Dream Bubbles of the Orange quality and higher have a chance to drop Profound Dream Talking, which can be used to add advanced Dream Affixes to your gear during Dream Interpretation.

Dream Omens
1. There are 2 types of Dream Omens: Sweet Dream Omens and Nightmare Omens.
2. Sweet Dream Omens will change your Dream Bubbles in various ways, such as by changing the quality or type of bubbles, and adding or removing bubbles.
2.1 When choosing an omen for the first time in each round of dreams, the Sweet Dream Omen that appears is called the Fundamentals of a Sweet Dream, which usually takes effect multiple times in subsequent choices or when entering a Nightmare.
2.2 Sweet Dream Omens that appear from the second choice onward usually take effect immediately.
2.3 When taking effect, unless specified otherwise, Sweet Dream Omens will not automatically avoid situations where they can have no practical impact. For example, an omen attempting to upgrade a bubble's quality might still target a max-quality bubble, failing to produce an effect. An omen attempting to add a bubble will still try even if the vision is full, also resulting in no change. Please consider your choices carefully when choosing Sweet Dream Omens.
3. Nightmare Omens will enhance your Nightmare in various ways. When you enter a Nightmare, all the Nightmare Omens you have chosen will take effect simultaneously.
4. Every Sweet Dream Omen is accompanied by a Nightmare Omen. Be sure to carefully evaluate the associated Nightmare Omen when making your choice.

Nightmare Trials
1. In a Nightmare, you must defeat all Nightmare Roots to make your dreams come true.
2. Whenever you are defeated in a Nightmare, you will randomly lose 1/6 of your total Dream Bubbles (rounded down). The portion that has been rounded down will be recorded. Once the total rounded-down portion reaches 1, an additional bubble will be deducted when you are defeated, the remaining rounded-down portion less than one will be recorded, and the process will keep repeating.
3. Bubbles will not be deducted immediately. Instead, all bubble deductions will take effect when settling the successful or unsuccessful escape from the Nightmare.
4. The Nightmare stage inherits the base drop bonuses from one random map within the current round of gameplay (excluding bonuses from Netherrealm Resonances, Compasses, and Cards). Its Stage Level is the average of all map levels encountered in that round.
