Recently I had an incident were I was lucid dreaming and there was a naked women in front of me. I did not immediately wake up until about 30 seconds into it. Could this be interpreted as porn therefore making it haram?
No, having lucid dreams isn't haram. Lucid dreams happen when people sleep. Actions during sleep are not recorded according to the following narration:
Narrated Aisha, Ummul Mu'minin:
The Messenger of Allah (ﷺ) said: There are three (persons) whose actions are not recorded: a sleeper till he awakes, an idiot till he is restored to reason, and a boy till he reaches puberty.
