Hello all im 24 years old

i started doing meditation (mindfulness) and somehow got to astral projection (with youtube videos) so -

i bought lucidology 102 - and after reading its a scam here decided to register here and see what answers i can get :

anyway and in short what i want to learn :

1 . I sleep walk hard to the point i get injured - can i stop it somehow with lucid dreaming ?

2 . i want to learn how to lucid with visualization without all the waking up going back to sleep tricks and without reality checks

or

3. i have manged to get to half sleep parlysis - where i dont feel the limbs and they go numb and the face also feels that way - BUT if i want to move a limb i can move it right away - how can i make this to a full parlysis ?
