Yes, these sensations can be extremely bizarre. Mine don't last too long, sometimes a zip, an hour, sometimes up to 2 days. I've had warm wet patches, cold wet,just warm or cold - but not wet, freezing toes (normal temp to touch of course) more intense small , localized buzzing, ears changing pitch,intense painful jabs into my ear, all kinds of bizarre stuff. So you are definitely NOT alone. Everyone on this site probably has some of this.
