Hi<br/><br/>Which of these sentences is more natural? Or are they all OK?<br/><br/><b>He had just gone to bed when the alarm went off.</b><br/><br/><b>He had hardly gone to bed when the alarm went off.</b><br/><br/><b>He had just lain down to sleep when the alarm went off.</b><br/><br/><b>He had hardly lain down to sleep when the alarm went off.</b><br/><br/>Thanks,<br/><br/>Tom<br/><br/><b>PS: What do we call the alram which means we should evacuate the building immediately?</b>
