I've noticed a little confusion in the chat with people worrying about which kind of learner they are.
The truth is that most people are likely a combination. Don't worry too much about fitting neatly into a label.
Remember that it is just a simple tool to help you work with your strengths rather than against them.
For example, MILD is great for visual learners but will probably be much harder for someone who is predominantly kinaesthetic (who would be better off using IMP).
The reality is that nature isn't as tidy as we'd like her to be.
Classifications are almost always simplifications—don't mistake the map for the territory.
We're all unique and complex creatures, but it is useful to have a rough yardstick to work with so that you can tailor your choice of techniques. You don't need to follow complex tests online to establish your type, for the needs of lucid dreaming the following test is enough:
Which is easier for you to imagine:
1) The image of a hand.
2) The feeling of your hand opening and closing.
3) The sound of your hands clapping.
For me, 2 and 3 are much easier than 1.
Therefore I am a combination of auditory and kinaesthetic, so I will always try techniques that lend themselves to those strengths first.
It really needn't be any more esoteric than this. Observe and understand your strengths and weaknesses and pick techniques that suit them.
