In a bowl, soak the oats in water (make sure they are covered) for no longer than 15 minutes. Drain them and rinse thoroughly under a running tap until the water that comes through the sieve is completely clear and no longer cloudy.
Add the drained and rinsed oats into a Vitamix or high-speed blender with 3 cups filtered water and vanilla essence if you choose. Pulse for a minute until completely blended.
Pour this liquid through a sieve. The first time you do it, there will be some residue that you should discard (keep the milk below it). Repeat the process a second time, and then a third time until there is no residue left in the sieve.
Transfer the milk into a sealed container and store in the fridge for up to 4 days. It will separate so stir before you drink it.
