No Sal Casteneda, you're not going crazy. The U.S. Geological Survey confirmed your suspicion Friday night when they reported a magnitude 2.8 earthquake, 1.86 miles northeast of Oakland.
The temblor on the Hayward Fault line was at a depth of 4.9 miles and the shaking was reportedly weak. Still, it was enough to get our traffic reporter's attention.
On Twitter, Casteneda tweeted, "Was that an earthquake?" one minute after it happened at 10:41 p.m.
There were no reports of damage, but phone calls came in to the KTVU newsroom from Alameda, East Oakland, Oakland's Grand Lake Theater and in San Leandro where a child apparently screamed.
We will update this story with any more details as they become available.
