The first time I Let Ginger sleep in my bed.. I almost killed her

I had taken a sleeping pill (long story).. and i had fallen asleep.. and my tendancy is to put my leg on something.. like a pillow in between my legs.. or put my leg on my boyfriend

..
But she had crawled inbetween that space.. and i ended up putting my leg on her.. and i didn't know cause i was knocked out cold lol.. my boyfriend was the one who woke up (thankfully).. and woke me up cause Ginger was under my leg and the blankets gasping for air.. i felt like a terrible person... but Ginger forgave me.. Ginger still sleeps with us.. but either sleeps at the edge of the bed.. or on my head lol..
But I sort of want them to sleep in their own bed.. Any ideas?
