Introduction
Claire's dream in-game is a random set of minigames that can be played inside some sort of dream sequence and depending on how well you do inside the minigames you are given better rewards. The rewards themselves seem to be set by the game but the chance of which one you'll cquire is random and the chance of getting a claire's dream machine is also random.
You can only acquire Dream Machines however only 7 times a week.
Acquisition Guide
Where you can find a Dream Machine
You can find Dream Machines from opening Rusted Iron Chests and also killing mini bosses.
Fastest way to find Dream Machines
I recommend simply exploring as it's a lot more simple for you since you can find chests while trying to get gold or black nuclei. However if you are strapped on time I think that area is among the best areas as there are multiple mini bosses as well as an open area to easily see Iron Chests.
Varying Mini-Games
Survival (Mob Waves PvE)
Gameplay here entails you fighting a random assortment of mobs. To acquire all of the rewards you'll have to defat 70 enemies. The main rewards you'll have to stay alive for at least 3 minutes on the field.
Overall it's a forgiving dream sequence and not very hard, if you lack DPS or AOE you may not make all the rewards but acquiring the main reward is not very hard thankfully.
Fairly easy, just have to have AOE and make sure to use Relics.
Matching Mini Game
Matching gam, simple to understand, all you have to do is match the toys or animals with each other. It's a bit unforgiving if you're bad like me or just get a bit unlucky. Otherwise you should be able to at least get 2/3 rewards as well as the main reward.
Not too hard though you can get unlucky.
Parkour
Or if you're more familiar with the the name jump quest you'll understand as you simply just have to make it to the end destination within the specified time limit. The time on the top left can be extended when you get to the timer checkpoints. If you happen to fall off you do not instantly lose you simply go back to the previous checkpoint.
Forgiving enough, you should be able to get all the rewards.
Shooting Challenge (Target Practice)
Shooting the targets, some of them move and those tend to be the one where you can get the most points. You are not penalized for missing for feel free to hold the mouse 1 button.
Some of the targets do move at times but the game will spawn so many that you should not worry much about those.
Values for each of the targets: Blue: 10 Green: 20 Red: 50
Easy if you're on PC, even on mobile and controller you can spam M1 and do well.
Maze
You'll have to go through a maze minigame and the better time you get the better it is in terms of rewards.
2D platforming
Similar to the older side scroller games you'll have to go through the map within the designated time and also collect orange nodes that is across the map. The game itself is very forgiving and you'll have time to collect a lot of the nodes, I would not worry about missing a few nodes here and there as they give you more than enough.
Rewards
The rewards vary and we'll more than likely miss a few but they seem to be hard set rewards but it's random which reward you'll get for which specific minigame.
Here is a short list of what you can potentially acquire:
Matrices, Gold Nuclei (w/ dark Nuclei as sub rewards), Relic Selector, R Equipment Box, Proof of purchase (w/ Matrics as sub rewards), SR Matrix Pieces.
