Since I was quite young my Mum has told me and my siblings about her encounters with aliens, how they have abducted her etc. (she says its the grey ones with almond shaped black eyes) As a child I was petrified of the dark, in fact I was until I moved in with my DH aged 19. 
She tried to talk to me about it again the other day - in front of my DS who is 2.6. I quickly changed the subject, I really dont want her frightening my DC as well.
My Mum is generally a lovely relatively normal lady but I cant get my head around this. I dont want her to talk about anything like this around me as it freaks me out! My siblings are the opposite and are happy to chat with her about it.
Do any of you know someone who has had alien encounters or have you had them yourself?
Am I being unreasonable or would it scare the pants off you too?
