Smelling burnt toast

This is the second time in the last month that I've woken up in the middle of the night because it smells like burning toast. I end up freaking out and sending my husband to see if the oven or stove got left on, but he never smells anything, and everything is turned off. Has anyone else experienced this before? I'm concerned because Google comes up with a giant list of scary things it could be. Also, right now I don't have a general practitioner I can see. Sadly my doctor died this past fall, and I hadn't found a new one yet, and with COVID right now, it doesn't seem safe to try to find a new one. Has anyone experienced this before? Is this something to tell my OBGYN, or will I just sound crazy?
