I'm glad you're OK, Richard.
I think the bathroom would be safer than outside unless you live in a mobile home, in which case lying in a ditch outside would be safer.
You want an interior room, closet, or hallway on the lowest floor you can get to so you can't be hurt by broken glass or falling debris. When I was a kid and a tornado passed overhead, we dragged a mattress into the interior hallway so it could protect us from falling debris, but the tornado didn't hit our house but hit many others in town instead.
My brother's house was hit by a tornado when his wife was home alone and he was at work. She huddled in a closet and was OK. The house they live in now has a basement and they go into it if there's a tornado warning in their area.
