Ghost kicks

Most people will probably think I'm just crazy, but I'm curious if I'm the only one. Has anyone else ever felt "ghost kicks" it feels as if it's a baby kick but you know that's impossible?? I felt them a few times after already giving birth to my daughter, and now I am a little over 5 weeks pregnant and SWEAR I've felt quite a few kicks, which I know they obviously AREN'T it just feels like it. Anyone else???
