Lights keep appearing to me

Hi,

a few weeks ago I saw a white pillar of light hanging in the air in my living-room. I saw it for a few seconds until it slowly faded away. Then couple of days ago I saw it again, although this time it wasn't as much of a pillar but more like a rag or cloth of white light that hung in the air for a few seconds. And yesterday I saw three tall and thin pillars of white light flash in front of me for about three times.

A friend of mine told me that something or someone is trying to manifest itself to me. Have any of you had similar experiences and if so what did the lights turn out to be?
