Hi Lilytear,
you are not crazy. I went through similar type of experience. I lived in a house haunted by some spirits. The time when they tried to deliver some messages then light bulbs of room became dim, continuous on/off and wind in the room became cold.  Some one walking around you,  is also beleived.

i read somewhere that the incidences of lights and light bulbs flashing, dimming and dying are occurences of 'higher' spirits and not necessarily benevolent. These spirits apparently permeate a greater energy source subsequently affecting any electrical appliances around.

okay I know that this topic is not new... But I wanted to add to it, For years now, EVERY place that I live I have frequent power blinks... just sitting watching tv, playing cards, cooking dinner, taking a bath you name it and I have been doing it when the power would go off and right back on. Now while this is not completely unusual in Florida, the amount that happens in places I live is. My b/f's mother lives in a house that I used to live in and she has had No out of the ordinary problems since I have moved into my apartment, though my apartment, and ONLY mine (none of my neighbors have these problems) seems to keep up the tradition of it. I have also noticed that when I am really angry or annoyed that the bulbs in the house blow... It has gotten a little better since I have been doing more things outside of the house... (like at my friend's house) But now she is getting them too..... After I leave for about a day or two... Lol sharing the love right?
