Can I Use MILD To Choose what kind of dream I want

Let me explain in more detail, I want a dream about going to a land of teletubbies :D (just an example)
Can I do this in MILD by repeating "I want a dream about teletubbies" or something along the line
Thanks :D

While I haven't tried this myself, you would want to say " I am having a dream about teletubbies" or "I will have a dream about teletubbies" as a mantra, if you were to try this. saying "I want" just probably isn't strong enough.

Yes, you can have a MILD if you really push for it to be a mantra.

Much like loik said, you should use "I will" instead of "I want". "I will" might not envoke the confidence you need to do it.

If the intention is to be lucid whilst you have that specific kind of dream, then you could also use generic MILD mantras to actually get a lucid dream, and then in the dream teleport to wherever you want to go (that you're imagining the dream you're thinking about would be) and let the dream unfold in front of you.

(but, you know, loik's solution would probably work too.)

If you have an interest in dream incubation, I think visualization has a stronger effect than mantras. Mantras have more to do with prospective memory. Mantras can help you maintain focus while visualizing but the content of dreams is more influenced by sensory (visualization) and symbolic (schema) input. For me, WILD with visualization has the most success for incubation. The other option is DILD (any style) and then using visualization and schema dream control to change to the desired scene.
