G'day,

To add to what has been said here....

If you cannot see, make firm commands 'Sight now! and 'light now!'

Repeat as necessary.

This works through your higher self. Results are generally instant.

Affirmations prior to OBE exit, daily until resolved, will also help enormously, eg, 'I see clearly in the astral' and 'my out of body experiences are bright and clear'.
