Here is the craziest incident to date. I have an apartment in Belladonna Cove with two of my sims. I have a roommate in addition to that. She is very high on the nature enthusiasm so on many occasions she will go outside of the apartment building and sniff the flowers outside. Here is where it gets good! She will sniff the flowers, stand up, get the 'in the zone' glow, and then repeat all night. On several occasions she will do this from 10 PM to 4 AM nonstop sniffing flowers. The 'in the zone' glow makes a weird sound, so when I am unsuspecting I always think something bad is happening. She does this several times per week.
