I have 12th lord Venus with Rahu with Venus being starved sitting at 3rd house, Mars starved by Me in Gemini, a good sleep is a rare thing to me, even vacations are just like brainstorming events, even though I like it, I bit more yearn for just relaxing somewhere isolated, which also very rare thing! Whenever a good sleep happens, I am extremely grateful! drinking too many cups of tea or coffee in a day doesn't help for sure, even though recently I noticed even a second cup of either one in a day can ruin my sleep!
I also have 12th lord Venus conj Rahu and a lot of 8th house stuff (LL Mercury, Saturn, Uranus, Neptune). I have very fragmented sleep. I frequently have hypnopompic hallucinations, unintentional lucid dreams, etc. I’m grateful for them because they developed into healing opportunities rather than terrors. Once in a blue moon I get visits from guides that are very different than a normal dream. Once I was told to look out for a bear and the next day I had a black bear at my front door. 😆 I did have one intense period of insomnia that was not fun because it caused mild seizures.
