Black & White Dreamy Effect

First find the image that you would like to apply this effect too, I am going to use an image that I took when I went to Florida this past summer.

1. Open the image in Photoshop.
2. Apply the following; Image > Adjustments > Auto Levels.
3. Next; Image > Adjustments > Desaturate.
4. Duplicate the layer and with the top layer selected apply the following; Filer > Blur > Gaussian Blur with a radius of about 4 pixels.
5. Finally change the Layer mode from Normal to Overlay.

Please view the bottom images to see if you had a similar effect.
