A childhood belief about under my bed

i used to believe that their was an old lady tortoise who lived under my bed. and though she was really nice, and told me not to be scared of her, i could never let my arm hang over the edge of the bed. she would give me advice, and was very much like a grandmother figure to me. (i do have a gradmother, and we have a very good relationship, so i don't know why i also had a tortoise... maybe cuz i didn't see my grandma all that often...)

then one day when i was about 7 or 8, i finally got the courage to let my arm hang. (i had always wanted to touch the tortoise's shell and skin and see if it felt the same as my real live pet turtle, who i'd had since i was 4... and i still have now - i'm 18) but i fell asleep before she reached me (cuz tortoises are slow) and she never came back again
