How I will forget that Sandal Aroma?

I was sleeping peacefully. Breeze from neem tree near my window was cool. Moon was hiding behind the clouds. Was the moon shy or afraid something going to happen. It was past midnight and the whole world was resting. No traffic, no sound and no one was awake. In my sleep I felt someone was watching me. 

I thought I was dreaming. Suddenly I felt mild sandal smell inside my room. The aroma was thickening enough to wake me from sleep. I woke up and was thinking logical reasoning behind the smell. No one will be bathing or using perfume at that time. It was nearly 2 in the morning. I switched on the light. 

I have read stories that when ghosts came, with them jasmine smell will come. I thought this ghost was different, it was bringing sandal smell along with it. I was sitting in my bed waiting for the ghost to appear. After some time the sandal aroma was lessening and finally there was none. I switched off the light and went to sleep again. Have you faced such experience in your life?
