You can start by visualizing yourself interacting with him directly before a REM cycle (early morning). Wake up, use bathroom, get a drink, etc. Then in bed calmly visualize and form an intention to be lucid upon seeing him. See if that works.

In the meantime, check out Naiya's Simple MILD technique and Puffins-DILD-Guide (can't post links at the moment, you can search those up on the forum or Google them).
