I think it’s Great that you heard sounds as well from the people at the table! 
I’ve only WILD’d a few times, but my HH never involved sound, and no HS either. I would say you were very close to WILDing! 
I would recommend reading The WILD FAQ from the ld4all knowledge base. I particularly enjoyed the explanations of the differences between HI HH and just looking at the back of your eyelids 
Edit: As for SP, I too have never ‘truly’ experienced SP I think, as I know I can always move something if I choose to, however, I have WILD’d so I wouldn’t worry about it.
Best of Luck to WILDing and LDing, and
