Well...that was an awesome post! I've read about Vlad the Impaler, but I wasn't aware he(they) were associated with Dracula. You mentioned that he would have dinner with the impaled?
....does this mean while they were impaled? Before they were impaled?
...or he pulled the long spear out and let them eat dinner? (whilst the chewed food obviously just fell through the person and out their "spear hole")
Lastly, apparently the "impalement" would take about 3-4 days to kill the victim. The pole or spear would slowly make its way through their body. The Vlad's may have had unresolved issues...
